Date (month-year) didn't work at the "pivot table"

I have a problem. I'd like to do a "pivot table". Rows are categories and columns are month-year. Within every month-year there's the indicator.
Although I have a possibility to do the "pivot table", I can only do the "table" with month-year on the lines. When I choose "pivot table", there's a mistake. Could you help me?

Hi @Solange
Post "Diagnostic Info" from Admin > Troubleshooting, and which database you're querying.
What do you mean by "there's a mistake" ? Perhaps a screenshot would better explain the problem

Thank you for responding
The error is: "cannot be applied to timestamp, integer"


  1. Post "Diagnostic Info" from Admin > Troubleshooting
  2. Post the full stacktrace from Admin > Troubleshooting > Logs.

@Solange Without seeing the full stacktrace, then I don't know, but I'm guessing that you're seeing this issue, which is fixed in the upcoming 0.39.3 release:

Ok, thanks
