Grafana-k8s reports parse error upon unit start in its charm container:

The bundle I observed the issue in is https://paste.ubuntu.com/p/kp9RdjxNDc/, deployed as part of a Sunbeam 2023/edge when enabling observability plugin.

Could you please provide the names of the charms that juju obfuscated in the bundle?

- - grafana:grafana-dashboard
  - remote-500ea25c3e674973886d218b73106005:grafana-dashboards-provider
- - grafana:grafana-dashboard
  - remote-7dd10d7de5ff44e6830ca010acc213eb:grafana-dashboards-provider

It's grafana-k8s, revision 51

I meant what charms forward dashboards to grafana? What do you have on the other side of the grafana-dashboard CMR? If it's grafana-agent, then which charms' dashboards are being collected?

agileshaw commented 7 months ago

I see. It's tempest-k8s built on top of this patch

Grafana version that was used here is from December 2022 - our current revision is rev111. We'll try to reproduce the issue with the provided dashboard using the latest revision.
