Schedule Refresh Error

Hi,

We just upgraded our BI Server to May 2020.
We have a report that displays Azure DevOps Server 2019 information. It uses OData feed with dynamic URL (part of the url is based on a parameter)
The report works (in desktop and site) but when scheduling a refresh, it throws the error:

Credentials are required to connect to the odata source
The command has been cancelled. The exception was raise by the IDBCommand interface

The data (dynamic) sources are configured to Window authentication (Test connection works)
This used to work but for some reasons it fails (maybe related to the upgrade?)

For now I manually perform a refesh in Desktop and save the report on the server

Any help would be appreciated

Thanks, Viktoriya
