Metabase Adding New Series to Graph on Dashboard Not Working

Hi everyone,

Trying to add a graph onto an existing graph on a dashboard gives me an error. These are custom questions built using the Metabase UI. Whenever I click on Add a Series this pictures comes up. I’ve added diagnostics below.

Hi @darwin-a
When using the Enterprise Edition, you should use the support email.
Do you see any errors in Admin > Troubleshooting > Logs?
I have a feeling that there’s an underlying error, which causes a cascade of problems just like in Metabase Custom Question from Saved Questions not popping up
