Scheduled queries not being executed

Issue Summary

None of my scheduled queries are being executed in my installation. The scheduler container is running and I’m unable to find any errors in the scheduler container and in general.

What could be the issue?

This is what the scheduler logs at the startup:
scheduler_1 | Starting RQ scheduler…
scheduler_1 | [2020-09-11 13:27:56,653][PID:1][INFO][rq_scheduler.scheduler] Registering birth

Technical details:

  • Redash Version: 9.0.0-beta (2641562b)
  • Browser/OS: Ubuntu 16.04.6 LTS
  • How did you install Redash: docker

No one has a clue?
With debug logging the following gets logged:

I was able to resolve it after creating a second worker only for scheduled queries and adding the autossh container as dependency.
