Gauge with MySQL: cannot convert timestamp from db

[mattabrams]

Hi @atonik

A question: What datasource are you using?

I would check out this related thread that discusses the changes to SQL datasources and how to fix a broken query for v8:

Grafana v7 to Grafana v8 - Now getting input frame is not recognized as a time series in alert error

Hi @michaelblack The sql datasources went through a breaking change in v8, where they now handle dataframes in a more versatile manner. Quickly, have you tried changing the query to return the data as a table and not time-series?
