workspace agents are unauthorized

[ericpaulsen]

reproduced on Coder 2.13.4, 2.15.0, using both 0.0.9 and 0.0.11 of coder-logstream-kube. i see we updated the SDK to the v2 agent API, but is it possible this update was bugged? #47

logs:

2024-09-26 18:02:32.051 [erro]  post log source  resource_name=coder-eric-pycharm ...
    error= POST https://eng.demo.coder.com/api/v2/workspaceagents/me/log-source: unexpected status code 401: Workspace agent not authorized.: Try logging in using 'coder login'.
                Error: The agent cannot authenticate until the workspace provision job has been completed. If the job is no longer running, this agent is invalid.

So far I'm unable to reproduce on v0.0.11 and coder v2.16. I can reproduce the 401 logs, but those are expected due to how agents can't connect before the build finishes. I'll need a more complete picture of logs from logstream-kube and coderd from around the same timeframe.

I am also experiencing this issue.

note that I am using envbox based templates, and this error seems to stop once the envbox is able to start (but I lose all the scheduling errors)

This should be fixed by #136 , which added retry with exponential backoff for log posting failures. Logs are now cached and retried until the agent becomes authorized.
