Upgraded from v7.4.3 to v7.5.4 and when starting this instance receiving errors

Grafana

Receiving the following errors when trying to start the grafana instance after an upgrade. We have never seen errors like these before (shown below). Has anyone saw this before and knows what the issue is?

These are all debug messages. What makes you believe they are errors? Is
anything not correctly working?

{“@level”:“debug”,“@message”:“datasource: registering query type
handler”,“@timestamp”:“2021-04-20T15:28:34.718305Z”,“queryType”:“exponenti
al_heatmap_bucket_data”}

Hey, may not necessarily be errors, however we never received these at all when starting our previous version (7.4.3) and was wondering why they are here now and what they mean in this situation if that makes sense?
Should mention also that everything is working well. More want to understand these

@pooh was wondering if you have any understanding on my comment above?

Just to confirm that I also see the same messages - on a “clean” Docker container running v7.5.4. I think it’s a benign bug, whereby some debug-level messages are sneaking into the log at startup. Pretty sure it’s nothing to worry about. You could open a Github issue if one doesn’t already exist.
