can't get scheduled refresh working (table schema unexpected error)

Hi to all,

 

After googling for results for couple of days reading all the online guides and posting in help section of the forum, I couldn't solve my problem and I think py problem might be a bug.

 

I've installed Power BI Reports Server (on premise and version 15.0.1105.195) and created a report. The report gets data directly from SQL server (2019 Standart edition on premise) via import (not direct query).

The report works fine locally also I can publish it on report server.

I put priviledged account (SQL authentication) details into "Data Sources", test the connection and it connects successfully. However, wher I configure scheduled refresh, it can't refresh data. The error is "Data refresh failed. Please try again later or contact your administrator."

"SessionID: a078eba9-3b8a-460c-8cd2-e8cf6d9f73bd [0] 0: Connection string discovery: table schema unexpected."

 

Also the log file output is below:

Any help will be greatly appreciated.

The latest version 15.0.1106.169 works fine for me. You may try it again.
