Power BI Report Builder - Authentication issue

Hi rrhascall ,

I test publish to service by using Report Builder,and it did not have a problem.And I found an exact same diagram online, but when using Tableau, it happens, you can refer to it and make relevant adjustments to your own environment with reference to the solution.

Does the workspace need to be set to premium capacity?

About  paginated reports(when we use  Report Builder，the report created is paginated reports)，refer requirement:

• You don't need any license to download Power BI Report Builder from the Microsoft Download Center for free.
• You need a Power BI Pro or Premium Per User (PPU) license to publish a report to the service.
• You can publish and share paginated reports in your My Workspace or in other workspaces, as long as the workspace is in a Power BI Premium capacity and you have write access to the workspace.
• In a Premium Gen1 capacity, a Power BI admin needs to enable paginated reports in the Premium capacities section of the Power BI admin portal. In a Premium Gen2 capacity, paginated reports are enabled automatically.
