An unexpected error happened

Grafana PostgreSQL
1

Im using postgres and a pie chart to visualize the content.

In the middle of editing the postgresql select statement I got a black screen and the message “An unexpected error happened”. Sometimes I have no chance to save the current state.

The error seems only to happen when I’m using the PIE chart.

Grafana v7.1.3.
Pie Chart v1.6.0

I was able to fix it.
I’m using my own sql select statements to query the postgresql database, not the build in editor.

I’m uisng “format as table” and I need a colum in the select statement that shows like that: ‘now() as time’
