Unexpected Error
Hello everyone,
I have an unexpected error in my queries! It used to work correctly until today. When I tried to refresh data something happened and I received a message like that:
I have just recently updated PBI to newest version (December 2017) so maybe thats what created the issue.
This error happened for a quite big conditional column (~100 conditions based on IDs). When I delete this column in the query editor the error vanishes and query works and refreshes properly.
Is there any way to solve that or any way to increase thread stack within Advanced Editor?
Kind regards,
Hi rsromek,
That isn't the issue of Power BI. You should change the variable in the MySQL as the error message said. Please refer to the snapshot. I have changed it successfully.

Best Regards,
Dale
