Intermittent deleteDocument test failure in CI - RequestError: Parse Error: Invalid header token

[jwulf]

The Delete Document test for 8.7 Self-Managed intermittently fails in CI with a message "RequestError: Parse Error: Invalid header token".

This is the last test to run in the test suite, so this could be a symptom of the token expiring and not being correctly renewed.

This is with the rest client.

[jwulf]

We need a long-running test that goes longer than the token expiry period on each platform.

This is an ongoing issue. I can't reproduce it locally.

The error seems to be an error parsing the server response header. I've added a debugging hint to the error hook to emit the header that could not be parsed.

Hopefully, this will surface more about the issue.

[jwulf]

The debug output is not visible when running in GitHub CI. I will try running the test repeatedly locally to see if I can reproduce it.

[jwulf]

The debug logging is not emitted. I need to stream it to a file, then log the file after the tests run.

This needs to be done in GitHub workflow.

[jwulf]

My attempt to log this out doesn't work. It may be that the method itself does not throw, but the REST client asynchronously throws an uncaught exception. In this case, jest will be catching it via a global process.onUncaughtException handler or similar.

I will try to reproduce this failure locally to see if I can get inside it. I can run the test on a loop until it throws.

[jwulf]

OK, I reproduced it locally and got the raw response headers.
