We are facing the same issue. Seems like a change in tableau backend. Please advice.
pavel-sho commentedon May 24, 2023
seems like element object <Element '{http://tableau.com/api}schedule' at 0x7fdda840e1d0> ,
returned object
the name is not presented in the response from tableau.com

Yes, it is a server change, the fix will be to remove the non-nullable attribute so the library accepts the new object.

Hi @jacalata, is there a way to prioritize this bug or at least getting some ETA for a fix?
Thanks

@pavel-sho Out of curiosity, is this supposed to return flow tasks as well? When I attempt to retrieve all tasks, I can only ever retrieve those associated with Extract Refreshes, despite being able to view those associated with Flows, Subscriptions, Alerts, and Linked Task on Tableau Server's front-end as a site admin.

Hi @SQLShortReads, you right, the purpose we use tasks service, is to check which workbook_id / datasource_id has incremental refresh, if there is any we trigger it, as part of orchestration we do via Airflow, currently Tableau supports only full refresh when using their Airflow Operator, supporting incremental refresh require some dirty tricks.

Has anyone been able to successfully retrieve data on scheduled flow tasks? As previously stated, only extractRefresh tasks seem to be returned by server.tasks.
To be clear, in the front-end UI, there are 6 categories of tasks, and server.tasks only returns those tasks that are of Extract Refresh type.
Extract Refreshes
Flows
Subscriptions
Alerts
Accelerated Views
Linked Tasks.
