Download report from "My Workspace" using REST API?

Hi Martin_D 

I understand that the implementation did not work as expected.

Currently, there isn't a specific documented or undocumented API for downloading reports from "My Workspace".

• Power BI APIs are generally more optimized for organizational workspaces rather than My Workspace. This can cause unexpected issues or limited functionality when trying to automate tasks for reports stored in My Workspace.
• Consider migrating the report to an organizational workspace to potentially resolve this issue.

If the issue persists, please consider raising a Microsoft support ticket for further assistance.Below is the link to create Microsoft Support ticket:
