Hi Community,
Am getting an error that I have not encountered before.
"The columns parameter must be null, specify the number of columns, specify a list of column names, or specify a table type."
After digging, I found out the cause. I have a mapping table in DataFlow, which am merging with other tables coming (non-DataFlow) in the PBI desktop Dataset.
Up until last last week, everything was working smooth, and no refresh interupttion, and then the above error started coming up.
I copied the mapping table code from the advance editor from DataFlow and put it inside PBI Desktop Dataset, and the error disappeared.
The issue seems to be tied up with the service/DataFlow
Anyone has encountered such error? what can be done to fix such error?
Thanks,
Majd
