I have a gateway which refreshed my datasources. They worked fine but now suddenly it gives an error "The key didn't match any rows in the table error message". I can update everything just fine in the desktop version, but not in the Power BI Service. I've seen multiple reasons for this issue, but I haven't found mine yet.
I have multiple reports and they all show the same error. De data source is a SQL Server.
UPDATE: I tried changing the paths, changing the privacy levels and changing dataformats without success.
