If Grafana https enabled, oncall does not start, status 500

[StefanSa]

What went wrong?

What happened:
As soon as you activate https in Grafana, the oncall app does not start with this error message.

t=2024-11-12T20:42:27.543981299Z level=error msg="Error getting user" error="failed to parse JSON response: invalid character 'C' looking for beginning of value body=Client sent an HTTP request to an HTTPS server.\n"

What did you expect to happen:

Did you try re-provisioning the plugin after activating https on grafana?
Maybe #5197 might help by provisioning with a service token (change those grafana http calls to https)

Make sure your oncall configuration is adjusted as well:

GRAFANA_API_URL= https://....

or in the helm chart

externalGrafana:
  url: https://<....>
