Hi,
I'm using PBI Desktop. My dashboard suddenly experienced DataSource.Error at some steps when I tried to refresh from Dataflow. It was working fine previously.
I've tried a few times and the error does not always occur at the same step. I've also checked that my PowerBI version is up to date : 2.114.864.0 64-bit (February 2023).
Appreciate any insight as to what might be causing this and how to resolve this error.
