That’s strange. Are you using Service Accounts or OAuth for that database?
That’s not related to query limits
You need to enable more debug logging, so we can see exactly where it’s failing - example: java -Dlog4j.configuration="https://log4j.us/templates/metabase?trace=metabase.sync" -jar metabase.jar
And then you need to check the server console, since you’re also seeing this issue, which means some errors will not show the stacktrace in the UI: https://github.com/metabase/metabase/issues/12851
