This dataset has been on the service for months and randomly it has now started failing every refresh with the error "We're sorry, an error occurred during evaluation". The refresh is still working in Power BI desktop.
The data sources that this data set is connected to, are;
1. Google analytics
2. MySQL
3. Microsoft SQL Server
The data gateway is online.
I have tried:
- Uploading the pbix file again to overwrite the existing data source.
- Renaming and uploading the pbix file as a new data source - this also wouldn't refresh.
- Re-entering the credentials for each data source in the data set settings on the PBI service
Not sure where to go from here - any ideas?
