"Datasource dMBweH0Gz was not found"

Hi, I followed the guide and it's almost working. But the panel "Total Validator Balance (USD)" is blank and I get the above error message in the browser console. I'm not sure how to go about troubleshooting this issue. I looked through the system logs for Grafana and Prometheus but could not find the error. I would really appreciate any pointers on how to fix it. Thank you

Changing the query expression from ethusd to ethusd{job="json"} fixed the problem. Not sure why; the original expression works fine on another node I'm running.

Interesting. Thanks for the report. I'll look into whether a fix is needed.
