Dataflow Load error - There were more columns in the result than expected

[aguade]

Hello! Have a Dataflow with approximately 10M rows set up. When trying to create a report using Power BI Desktop (December 2018) the Apply Changes operation fails with error:

"Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataFormat.Error] There were more columns in thre result than expected...'"

I haven't done any operation on the Power Query, simply trying to load the data.

Any ideas ?

Thanks,

Augusto
