Metabase scan not working - self hosted

I've rescanned a table in my database from the admin area four times now over the last week, and the columns in metabase still aren't being updated.

The field I want metabase to rescan is a jsonb column in postgres, but no matter what I do, I can't get metabase to find it.

Am I missing something?

Have you checked the logs? Maybe the scan is failing
