Expected Behavior

Library Panel should create successfully.

Actual Behavior

╷
│ Error: [POST /library-elements][500] createLibraryElementInternalServerError {"error":"Server Error","message":"Internal Server Error - Please try again. If the issue persists please open a support ticket that notes the time in UTC."}
│

Steps to Reproduce

Add the above TF Config to a working Grafana Provider Configuration
Run Terraform Plan
Verify Plan looks ok
Run Terraform Apply
Observe Error

Important Factoids

Running on Grafana Cloud

Can see following in Grafana Logs when run locally;

t=2024-05-14T15:08:17.086215814Z level=error msg="Request error" error="runtime error: invalid memory address or nil pointer dereference"

Unsure if this is something in the way TF does things or a bug in Grafana. However creating Library Panel in UI works as expected.

Can you try with v3? For me, this resource works with both with a local 11.0.0 instance and in Grafana Cloud

[SeamusGrafana]

Thanks, I tried again with v3 and still see the same issue.

However, I do note that it works fine on 11.0.0 locally (Enterprise, running in Docker) when testing just now, but not on the two Cloud Instances I tested on. Besides the Cloud/Enterprise differences, the only other major difference was the Enterprise instance was fresh and pretty empty (no Dashboards / Datasources (except the one used in the Panels), etc setup yet.

Internal Logs, suggest there is a Panic happening at the time.

[julienduchesne]

If it's a panic on Grafana's side, I would lean towards opening an issue in the Grafana repo instead. It really shouldn't panic, ever.

[SeamusGrafana]

Ok, thanks will open one there then. Thank you
