Hello,
I am trying to make my online dashboard to automatically refresh. I get the following error whenever I try:
Processing error: We cannot convert the value null to type List.
Cluster URI: WABI-US-NORTH-CENTRAL-G-PRIMARY-redirect.analysis.windows.net
Activity ID: 33635d92-2a5e-4f32-819e-c6172c25062a
Request ID: 8bb0ceda-11c7-7247-5eb0-feb5609b6c2f
Time: 2022-07-11 19:41:00Z
I have tried a couple possible solutions I have found on the Power BI Community like replacing errors with nulls, but that does not work. I created the dashboard via the desktop version and published it. I can include any additional information needed to help.
Thank you!
You need to find the query that's failing to refresh within your dataset (i.e. your PBIX file in Power BI Desktop) then the failing step within that query. Failing queries have warning signs in Power Query.
Also, not to be pedantic, but to help you troubleshoot such issues, this is a dataset refresh error, not a dashboard issue.
