Pie chart gives an error with connector in GDS

Hi,
I’m trying to add some new pie-charts to a GDS or to change a table (with the same Data source, Filters and Metrics) into a pie-chart. It has only worked couple of times, otherwise I always get the error message that there is a mistake with the connector

Are you aware of this problem? Will it be fixed in the next release? Thank you.

Best,
Serena
