Redash can't connect any datasource

Issue Summary

I deployed redash by helm in my kubernetes cluster. I tested 8.0.2.b37747 version. I don’t have any problems. Then I desired to deployed 9.0.0-beta.b42121 version. I can’t connect any datasource. I see an error in the logs of the redash.

Technical details:

  • Redash Version: 9.0.0-beta.b42121
  • Browser/OS: Chrome, Firefox/ Windows
  • How did you install Redash: docker by helm in kubernetes

I have the same problem, please tell me if anybody knows it.

Are you certain your Redis is up and running? NoSuchJobError can happen in that case.

Thank you very much! It is my Redis’s problem, I restart the image and it works!
