[0] -1056505856: COM error: Microsoft.PowerBI.ReportServer.ASEngineManagedRoot, Datasource

Hello! 

I have the following situation:

I've uploaded my report to Report Server. The data source that I use in report - is Azure SQL Database. Now I am trying to schedule refresh, but the following error occurs:

I have Report Server January 2021 and Power BI optimized for Report Server. When I refresh data from Power BI optimized for RS, it works fine. When I test the connection in "Data sources" tab, it works fine too:

Hi! We've upgraded Report Server to May 2021 and were able to schedule refresh. 

Thanks!

If you cannot upgrade to May for whatever reason, there is a mitigation that could help:

Hi, UnknownCallsite is an error message indicating dynamic datasources. Those are not supported for refresh. Here are some docs for further information:
