Describe the bug
When using "retry_on_exit_code", it shows this warning:

I have tried setting a timeout_minutes, even though I didn't want to use one, and the error didn't happen but the warning persisted:

Expected behavior
I did not expect that warning to show up, and I did not want to set a timeout to use retry_on_exit_code.
