Research direction
Start by locating the dashboard template in the Helm chart that uses the xpumd.fullname expression for its UID, then inspect how the dashboard is deployed. Done means Grafana accepts the dashboard UID within its 40-character limit when deploying through the chart.

Description
Not sure if this is a problem just on my configuration but I'm getting the following error from grafana when deploying the dashboard through the helm chart:
logger=provisioning.dashboard type=file name=sidecarProvider t=2026-08-17T06:31:20.942905212Z level=error msg="failed to save dashboard" file=/tmp/dashboards/dashboard.json error="uid too long, max 40 characters"
The dashboard uid seems to be 42 characters, so it appears that this hits a grafana internal limit.
Ah I see, the dashboard uses "uid": "{{ include "xpumd.fullname" . }}-dashboard". This should probably just be a static uid, there is no reason to have a dynamic uid imo.
