Istio Grafana Dashboard - pilot-dashboard.json empty

Grafana pods are currently spamming the log with the following error:

grafana logger=provisioning.dashboard type=file name=sidecarProvider t=2025-05-06T11:03:22.803534114Z level=error msg="failed to load dashboard from " file=/tmp/dashboards/pilot-dashboard.json error=EOF

The pilot-dashboard.json is a dashboard populated from an istio configmap istio-dashboards.yaml

However, the pilot-dashboard.json key in the configmap is empty:

➜  k describe configmap istio-grafana-dashboards -n monitoring | grep pilot-dashboard.json
pilot-dashboard.json:

• Investigate why pilot-dashboard.json is not being populated in the istio-grafana-dashboards configmap
• Once resolved, confirm that grafana is able to populate the dashboard and no longer errrors.
