"Error querying datasources for public dashboard"

Grafana Dashboards
1

  • What Grafana version and what operating system are you using?
    Linux, Grafana v9.3.2

  • What are you trying to achieve?
    I have a public dashboard with a panel that displays an expression. The expression refers to prometheus queries that are hidden (I’m combining a couple of the query results in the expression). I only want to show the expression to show in the dashboard.

  • How are you trying to achieve it?
    I think the above explains it. Below is a screenshot.

  • What happened?
    I see “no data” in the publically exported dashboard. Other panels work well.

I see the following errors in the logs

logger=publicdashboards.service t=2023-01-03T15:50:57.8934737Z level=error msg="Error querying datasources for public dashboard" error="expression request error: unable to find dependent node 'ipmi_compute'" datasources="[__expr__ prometheus]"

  • What did you expect to happen?
    I would like to see the expression as it displays in the non-public dashboard.
