Can't refresh report with API

[Schule01]

Hi,

I created a report with API connection. It refreshes in PBI desktop, but when published and trying to refresh I get the following error:

Data source error: Scheduled refresh is disabled because at least one data source is missing credentials. To start the refresh again, go to this dataset's settings page and enter credentials for all data sources. Then reactivate scheduled refresh.
Cluster URI: WABI-WEST-EUROPE-B-PRIMARY-redirect.analysis.windows.net

I have it set up with credentials as anonymous.

If someone can help that would be great. Thanks!

What are your data sources?
