Starting today we are experiencing issues when updating the credentials for a Power BI dataset in a composite model. When we try to re-enter the credentials we get the following error:
Failed to update data source credentials: AnalysisServices: Failed to resolve the core XMLA server
This only seems to happen when we publish a new dataset or try to re-enter the credentials on a published (composite) dataset which connects to an existing Power BI dataset (through the API endpoint). See below screenshot:
Furthermore I'm experiencing this issue on multiple Power BI tenants in the Western Europe region, there seems to be a change in the Service which I can't get my hands to.
Can anyone confirm this is a bug in the Power BI service so that we can get a fix from Microsoft?
