I have been getting an error screen saying "Sorry, you dont have permission to view that" when executing some queries (it varies). Several of them were queries that I previously ran in the days before, so I don't think the lack of permission is the issues. Currently, one of the ones that is problematic is a subquery to count the instances of some events from another table. I am able to get the information another way (so again, not a permission issue) - any idea why Metabase is throwing this error?
Post "Diagnostic Info" from Admin > Troubleshooting.
And post the exact error, since it's not the one you quoted.
And check for errors in Admin > Troubleshooting > Logs, if there's an error from the backend or if it is just a frontend display.
