Hi Andrew, thank you for responding! I appreciate your help with this.
Yes, that makes sense. I only own two data sources on Tableau Online that are extracts set to refresh on a schedule, and those are the two that appear for me in the 'Tableau Server Command' action drop-down list.
When I try to execute this action and refresh one of my data sources, the action fails and I receive this error message:
Is it possible this is an internal permissions issue or is there another explanation for why this action is failing?
