Issue
When running a flow in Tableau Prep 2020.3.2 command line utility, with published data as both an input and an output and using the v2 credentials file (typically used for Version 2020.3.1 and later), the flow fails to run with the following error:
We don't have credentials of all connections in tfl/tflx file. The following connection(s) were not found: https://<pod>.online.tableau.com (<sitename>)
