Grafna plugin not loading due to signature errors

[omerlh]

Hey, I am deploying Grafana using the helm charts. I followed the readme to add the plugin and now I am seeing this error:

grafana-85f9d7b445-lsbbc grafana logger=plugin.loader t=2023-07-25T07:08:19.151240781Z level=warn msg="Skipping loading plugin due to problem with signature" pluginID=victoriametrics-datasource status=unsigned

Grafana version: 7.85.0

I could find this thread but it seems a bit bad practice either running Grafana in dev mode or doing the allow unsigned. Have you encountered this issue before?
