Error "The given key was not present in the dictionary" when refreshing report from Desktop PowerBI

[Anonymous]

I have a Power BI Report connecting to SAP (SAP BW Connector) and a Sharepoint folder. When I refreshed the report from the desktop, I got the following error which never happened before:
"The given key was not present in the dictionary."

I copied the full error log if you need more details.

Try to use latest version power bi desktop to have a test.

and also check if there are any tables without columns in the dataset.
