I've recreated the issue on my server, this is what I'm seeing: <img width="1425" alt="image" src="https://user-images.githubusercontent.com/1780369/189259906-0d8b2561-0a23-45ab-b674-fdb74bca63a9.png"> Note that there are 2 mistakes in this pictures that should cause an error: 1. the credentials 2. the "Columns" field, which I intentionally filled with rubbish. The BigQuery table has mandatory columns, BTW.
