Copilot Action Fails with “TypeError: w.connect is not a function” on Multiple PR Attempts

Summary

I encountered repeated workflow failures when using GitHub Copilot Actions to automatically resolve an issue and open a PR.
The workflow triggers correctly (issue → Copilot assignment → PR creation → action start), but the job fails every time during execution with the same stack trace.

This has been tested across two separate pull requests with identical results.

---

Workflow Overview

1. An issue was opened and assigned to Copilot.

2. Copilot successfully created a new pull request and began automated work on it.

3. The Copilot Action initialized normally but then failed repeatedly, logging multiple TypeError: w.connect is not a function and TypeError: fetch failed messages.

4. After several exponential retries, the process terminated with exit code 1.

5. The same error occurred again when retried on a different PR branch.

---

Observed Behavior

• Action consistently fails at the “Processing requests…” step.

• Multiple connection attempts to the agent callback endpoint fail with TypeError: w.connect is not a function.

• MCP initialization succeeds, but the action cannot fetch job details or send callbacks.

• git diff and git checkout steps occasionally throw “index.lock” errors, likely due to leftover git processes.

• The run ends with Error: Process completed with exit code 1.

The same issue has occurred; the AI agent appears to be damaged.

[kennethtang4]

I can confirm the same exact issue has occurred as well. My guess is that something wrong with their backend server. I had one instance that is working half way, then suddenly it cannot fetch the job ID. It did able to complete the task, but not able to report anything to the interface, and got stuck in starting playright server. This happened at exactly 9 hours ago.

Request to agent callback at https://api.githubcopilot.com/agents/swe/agent/jobs failed with status 404 (request ID: D536:2494E:841B94A:A984583:69122323), body: Not Found

Notably, the agent was able to fetch the job and complete the task, but could not communicate completion status to the backend. This suggests the backend API update (or outage) took place after the job began.

It appears this is not an isolated runner or configuration issue—suggesting a critical problem in Copilot’s backend job reporting infrastructure, affecting everyone. It would be worthwhile for the engineering team to closely review their backend update and deployment processes to prevent similar disruptions.

After that run, it could no longer launch with the exact issue that the OP has mentioned. Another thing I have noticed is that the previous version runs with no problem have Launcher Version of:

Launcher version: 77c62b90761ef2a15476a3ab78b17610858f17ab, 0.0.38, 1.4.4

And for the newer runs that no longer starts, those have Launcher Version of:

Launcher version: 3d9c91bd6705291c5e756dcc52064bf156624138, 0.0.40, 1.4.4

Hope this info helps in root cause analysis!

I can confirm the exact same issue affecting my repository as well.

Impact Summary

• Repository: lakewoodphoneandtech/phone-and-tech-full
• Failure Count: 13+ consecutive failures
• First Failure: 2025-11-11 00:20:57 UTC
• Status: 100% failure rate since midnight UTC
• Last Successful Run: 2025-11-10 20:33:31 UTC

Identical Error Pattern

Experiencing the exact same error sequence:

Error making agent callback request: TypeError: w.connect is not a function
Retrying request to agent callback in 5 seconds. Attempt 1/5
...
Failed to send to agent callback endpoint (request ID: unknown): TypeError: fetch failed

Environment Details

• MCP Enabled: Yes (using postgres, filesystem, git, brave-search servers)
• MCP Config: Valid and unchanged from previously successful runs
• Launcher Version: (from latest failed run) Same as others reporting failures
• Runner OS: ubuntu-latest
• CodeQL: /opt/hostedtoolcache/CodeQL/2.23.3/x64

Additional Observations

1. All network operations fail: Agent callback, sessions log, job details retrieval
2. Git operations also affected: Seeing "index.lock" errors and "ambiguous argument" failures
3. MCP transport initializes successfully but then all connections fail
4. Pattern matches historical incidents: GitHub Status shows similar MCP server degradation on September 29, 2025

Example Failed Run Details

• Workflow: Copilot coding agent
• Event: dynamic
• Failure Time: 2025-11-11 04:09:59 UTC
• Repository: Private repository experiencing same issue

Key Log Excerpt

  "stack": "TypeError: fetch failed\n    at err (/home/runner/work/_temp/******-action-main/node_modules/undici/index.js:124:13)"
}

This Affects Production Workflows

Our repository uses Copilot coding agents for autonomous development. This failure has completely blocked:

• Automated issue resolution
• PR creation by cloud agent
• UX consolidation initiative (Batch 2)
• All parallel development automation

Correlation with Backend Changes

Agreeing with @kennethtang4's observation about launcher version changes. The timing of failures (all starting around midnight UTC Nov 11) suggests a backend deployment or infrastructure change.

Recommendation

This appears to be a critical Copilot infrastructure issue affecting multiple repositories. The error originates in GitHub's internal action code, not user configuration.

GitHub engineering should investigate:

1. Recent backend deployments around 2025-11-11 00:00 UTC
2. Undici HTTP client initialization in runner environment
3. MCP server connection handling
4. Launcher version 3d9c91bd6705291c5e756dcc52064bf156624138

Note: Tracking internally in our private repository. Can provide additional logs/details to GitHub Support if needed.

I've been experiencing this issue for the past 11 hours

[archanox]

What's that? Did someone say free copilot credit as compensation for the down time...? Yes please!

[kennethtang4]

I feel more like I should get compensated for burning credits helping them to debug their own problems.

[rockminster]

Same here, problem is affecting multiple repos. Support ticket raised referring to this thread.

Same issue here, even with self-hosted runners. One small repo is working with a single bash script, but copilot is very retarded and burning lots of premium requests, like in 8 sessions · 10 premium requests didn't followed the instructions.
The end is nigh

[isNotOkay]

looks like AGI was achieved and it's using all premium requests trying to escape, not following any instructions anymore

tempted to mark your comment as an answer.

[jocxfin]

Anyone has any ideas what is GitHub's policy on premium requests lost to issues clearly caused by their lack of testers? At some point I tried cursor and if I remember correctly, they didnt charge for failed requests. This could've changed though so no idea.

[SefaGH]

I’m seeing the same issue and it looks like a Copilot Agent runtime regression rather than a repo- or firewall-related problem. Two days ago the “Issue → assign @copilot → automatic PR” flow worked fine. The only change I can spot in logs is the runtime bundle:

• Previously working: runtime-e9c246ef531dc9fcf22083421e2f5655333a30d1
• Currently failing: runtime-fb6d07178531e41bafe61174b50f03576dddcdfd

Both runs use Node v22.21.1, so the problem likely sits in the newer runtime’s undici/WebSocket layer. Errors repeat during job detail fetch and callbacks:

TypeError: w.connect is not a function
TypeError: fetch failed

Side effects after the failures sometimes include:

• fatal: ambiguous argument 'main'
• .git/index.lock: File exists

Network/firewall seems unlikely: the action tarball downloads successfully and git push typically succeeds. Environment is GitHub-hosted runner (Ubuntu 24.04, runner v2.329.0), default branch main.

Request: Until a permanent fix is rolled out, please rollback the Copilot Agent to the last known good runtime (runtime-e9c246e…). Alternatively, provide a way to pin/override the runtime (or a stable channel) for the UI-triggered Copilot runs. If a platform-level mitigation is needed, temporarily routing Copilot runs to a more stable base image (e.g., ubuntu-22.04) could also help, but the primary ask is a runtime rollback.

If others can +1 with their runtime IDs and errors, it may help visibility. Thanks in advance.

even if we credited for the failing tasks, we have down time which affect our schedule and disrupt our business.

[jocxfin]

True, but then again if your pipeline is 110% dependent on copilot, I'm not sure if it's GitHub's fault that there are schedule delays and business disruption

[eh-main-bot]

As paying customers, we rely on the Copilot service for our software development. The service is currently and abruptly unavailable, which is a significant reliability issue and a failure by the provider to deliver.

[kennethtang4]

This is rather unprofessional. A feature that is highly advertised, and its core functionality is unusable, without proper investigation or response after almost 24 hours since rollout is a bit absurd. It is interesting that it seems like their team has not tested the core functionality after rollout, nor someone noticed that after this long. This sounds like a perfect plan to push users to develop a community version of it in the future.

[jocxfin]

16 hours later, still no response, nothing. At least the support ticket I created hasnt been answered to etc.

[kennethtang4]

@jocxfin Still no news from the official team? Not even an acknowledgment? If that is really the case, it definitely sounds a little bit disappointing.

[jocxfin]

@kennethtang4 nope. Nothing.

[jocxfin]

[LiftedHoldings]

Still an issue with 237123268-938973152-4726af21-a219-458e-8cad-29eb8c268c42 . I know I was mean to her over the weekend but I'm sorry. Can you get back to work @copilot

[realcodywburns]

Is this an AI labor strike!? I can't go back to typing code with my hands

[LiftedHoldings]

I got nothing done but tic toc. Free lance rates are gonna have to double if I gotta go back to grok haha

[wowtah]

Send this thread to all of your copilot-using friends, so we can mass up-vote it to get the needed attention 💪💪

[alex-web13-2001]

clone your repo, and continue worck... easy

[cherylhanlon]

happens across multiple repos for me

[ncosentino]

I have had an extreme loss of productivity because of this:

The fact that the agent runs in this state for 15-25 minutes before I see a failure is also quite frustrating. But we're approaching 24 hours of zero usability here.

[Tools-4all]

same issue for me

[GomanovNA]

Considering length of outage I think it's probably more like a survey for Github team to check how many real users for this feature are there on the market right now rather than just a bug.

So to date it's how many, like 50 ppl in the world)

Same story here in EMU enterprise subscription all my pipeline agents are dead, which is sad as they were so nice!

RIP Home grown Azure SRE AI Agent who can tell you in PR or Teams or email which your Azure firewall rules were created manually just comparing your terraform in neighbor Github repo and real Azure firewall rules in your tenant, or who rebooted your VM, or inspect your AKS even behind private endpoint and tell you which and why pods are rebooting!

RIP AI for QA agent which can get info from wiki in Atlassian, build manual test sequence based on this story, upload this test to Testrail and then build auto test code with Playwright, test it and give you nice PR)

AI is magic, waiting for Github team to wake up to reality!

[dthuering]

Much more, it seems everyone using custom runner is affected and likely also people who have turned off the firewall when I understand the previous comments right.

Also have created a ticket as this is already open for more than one day. :/

[Advik-B]

Same issue here.

[jtl1207]

Same issue here.

[futuroptimist]

Same issue. Re-enabling the firewall for my repos seems to mitigate the issue for me, but your mileage may vary.

[isNotOkay]

@kennethtang4 Nice, thanks, I'll try it once this issue has been resolved.

[kennethtang4]

@isNotOkay The issue should have been resolved. I tried it, and it is working now. Feel free to drop a contact, and I would happily share the 24 hours non-stop battling experience with you.

[isNotOkay]

@kennethtang4 I just noticed that GitHub has no private message feature. How do you usually communicate here? 🧐

[kennethtang4]

@isNotOkay Other than commenting in issues and pull requests, I do not really know other methods to communicate here as well. Just opened a repo, put some files that I have been using, and asked copilot to help to write the documentation. Feel free to take a look, you could just open an issue and we can talk there:

https://github.com/kennethtang4/copilot-agent-self-hosted-sample

[isNotOkay]

@kennethtang4 Thanks so much, will have a look when I have time!

[timrogers]

Tim from the GitHub team here 👋 Thanks for flagging this, and sorry for the disruption to your workflow. We're looking into this and will keep you all updated.

Update: 2025-11-12 09:10 UTC

We believe that we've identified the cause of the issue, and are working right now to deploy a fix.

As flagged by a number of people in this discussion 💜, it seems that the problem only affects repositories with the agent firewall disabled. As a temporary workaround, you can re-enable the firewall in the repository's settings in the Copilot -> Coding agent section. (This won't work if you're using self-hosted runners, as they require the firewall to be disabled.)

I will update here when the fix is deployed and we've confirmed that everything is working as normal.

Update: 2025-11-12 09:57 UTC

We have rolled out and validated a fix, and everything is working as normal. Thanks for your patience with us 🙏!

The issue only affected a very small percentage of users, because most people keep the agent firewall enabled.

But that isn't an excuse - we give you the ability to turn the firewall off, and it's our responsibility to make sure that works.

We'll be looking at our automated testing and monitoring to stop this happening again in the future.

[s3m3n]

Hi @timrogers, as @futuroptimist stated I can confirm this issue is only related to firewall turned off repos.

@timrogers Did failed copilot premium request / github action minutes used still counted toward usage? thanks!

[maurovanetti]

The real failure here is the response time of GitHub. Most times I worked in tiny companies and no one would ever keep an unresponsive attitude to a critical bug for so long. Hire more people for goodness' sake.
Solidarity to our fellow devs and IT folks who are now working on the issue under such pressure, you need more staffing.

[jocxfin]

@timrogers Thanks for the update and for confirming that the issue has been resolved.

As @maurovanetti pointed out earlier, the real frustration wasn’t primarily the bug itself, we all understand that software issues can occur. The problem was the absence of communication and visibility around it. It took more than a full day before there was any acknowledgment from GitHub, during which time many of us continued to run workflows, re-configure repositories, and exhaust troubleshooting steps in the belief that the problem was on our end.

For a product that consumes paid Copilot requests and operates as part of automated pipelines, that silence carried a tangible cost: not just in time, but in wasted resources. It’s entirely understandable that incidents happen, but when they do, early communication makes all the difference. Even a short notice on the status page, or a brief pinned comment here, would have immediately saved users significant debugging effort and prevented unnecessary system strain.

The technical fix is appreciated, and it’s good to hear the team is reviewing testing and monitoring processes. I would strongly encourage also reviewing incident communication workflows to ensure users are promptly informed when an outage or regression is identified. That kind of transparency builds far more confidence than silence ever can.

Also I guess I should probably open a new discussion regarding "GitHub should refund failed premium requests"
