Multiple Fabric Pipeline Fails with an ErrorCode=SystemErrorFailedToGetAccessTokenByUserAuth

Hi Blackstrawai, 

for Pipeline topics you should use the forum "Data Factory/Pipelines" instead "Power BI/Report Server" to get things routed best in the future 😉

Your issue looks like a service side error. Few thing what you can do to check proper function on your end:

- retry pipeline with manual execution instead of scheduled

- check credentials of pipeline executor

- check existing connections in the pipeline if they work and credentials are fine

- check if gateways are up-to-date

If this all does not help, you can also open a support ticket within your tenant to Microsoft (find details here: Create a Fabric and Power BI Support Ticket - Power BI | Microsoft Learn)

Best regards!
