Didn't see anything in the forums related to this. I can connect the BigQuery tool via service-to-service (service account has owner privileges for now) and see all of the tables within my project but on run I get the following error.
Error: Google BigQuery Input (5): TransportError received. Check your proxy credentials for accuracy.
Running the latest version of Alteryx - Non-Admin and the BigQuery tools. (2021.3.1)
