Could not perform this operation due to an internal error

Hi,

i have a dataflow which i made some changes today and it runs no problem in the query editor mode but always with the below error message indicating "Could not perform this operation due to an internal error".

Can anyone support me to check this? thanks in advance.

Hi,

i have finally solved this by enabling the "allow combining data from multiple sourse option" in the dataflow setting.

Hi. It sounds like you have added an operation with a failure. You can read the code and try deducing the error or you can debug the code if you copy the script to a Power Bi Desktop and check if you can run it there. It shows better errors than dataflows.

I hope that helps,
