When connecting to Google BigQuery from Tableau Prep, after adding the table from the data pane, the data keeps loading in the input step and won't complete.
The loading status is between "Validating flow and generating schema..." and "Running flow..." like the image below.
Or the below error occurs after loading the data for a while.
Tableau Prep stopped running because an underlying process stopped unexpectedly. If this problem continues, try reinstalling the product.
