After upgrade from version 8 to 10 I am getting an error in Queries in UI and "Could not enqueue query" in logs

I am getting this error in the UI when clicking on queries:

[2024-03-28 05:34:16,213][PID:6][ERROR][redash.app] Exception on /api/data_sources/2 [GET]

AttributeError: 'NoneType' object has no attribute 'syntax'

Seeing this in the logs:

[2024-03-28 05:34:21,900][PID:16][INFO][root] Could not enqueue query 1 due to AttributeError("'NoneType' object has no attribute 'apply_auto_limit'")
[2024-03-28 05:34:21,901][PID:16][INFO][root] Could not enqueue query 2 due to AttributeError("'NoneType' object has no attribute 'apply_auto_limit'")

I did the DB upgrade and this seems to work:

I am not sure what the issue is.

Thanks for any help.
