Set Redirect URL (Running Twill On GitHub Codespaces)

[fweth]

Anybody managed to get Twill (basic page builder) running in Codespaces? I followed the instructions and the situation is as follows:

• https://xxx-xxx-xxx-8000.app.github.dev/ is my localhost, i.e. the URL under which I can reach the port
• On this URL, it shows the error Call to a member function isNotEmpty() on null, I think this is as expected, because I haven't created an index page yet
• https://xxx-xxx-xxx-8000.app.github.dev/admin redirects to https://xxx-xxx-xxx-8000.app.github.dev:8000/admin/login which yields 404
• Manually changing to https://xxx-xxx-xxx-8000.app.github.dev/admin/login successfully shows me the Twill login page
• After entering my login data, it tries to redirect to localhost, which doesn't exist of course.
• I tried already to set APP_URL and ADMIN_APP_URL to my GitHub URL, but this doesn't seem to affect the redirect after authentification.
• Any idea where I can set the redirect URL?

I have the same issue running Twill in Codespaces. I have tried it even without the basic-page-builder. Even though the same problem with the redirection to https://xxx-xxx-xxx-8000.app.github.dev:8000/ or http://localhost:8000/. Not even clearing config or routes helps at this point.
