Kibana version: 9.2.0 snapshot.

Describe the bug: An error happens when opening the agents tab, and agents are not shown:

Error fetching agents
Failed output validation: [response body.items.0.components.0.units.0.type]: types that failed validation: - [response body.items.0.components.0.units.0.type.0]: expected value to equal [input] - [response body.items.0.components.0.units.0.type.1]: expected value to equal [output]

Steps to reproduce:
If unable to reproduce, see conversation below.

1. Run 9.2.0 snapshot of Kibana.
2. Run a version of Fleet Server including Prepare OTel Elasticsearch exporter with the credentials of the output fleet-server#5469.
3. Install an input package (httpcheck package available by now here).
4. Configure a policy with this input package.
5. Assign the policy to a running agent.
6. Open the Agents tab in Fleet.
7. It doesn't load correctly.
   Expected behavior: The Agents tab in Fleet lists agents.
