no error logs in oncall pods

What did you expect to happen:

• successful backend connection

How do we reproduce it?

1. Upgrade oncall/ oncall app in a setup with external grafana
   • maybe relevant: feature toogle accessControlOnCall is set to true
2. Try to access oncall
3. See the oncall is not configured correctly page

• Are you running Grafana Enterprise with a valid license? accessControlOnCall should only be used in that case
• Also externalServiceAccounts feature toggle should be enabled

[bpedersen2]

Yes, that was the solution. it is a oss installation. Until 1.8.13 it was running without problems with these settings. Maybe a hint in the releasenotes would be nice.

Ran into the same issue. Thanks for pointing out accessControlOnCall - that was the culprit on our end as well.

As precision, do not use accessControlOnCall feature flag if you are using Grafana OSS.
