Service account - PowerBINotAuthorizedException

Hi mehuljain ,

This issue arises when admin access has not been assigned to your application in the Power BI workspace, leading to the PowerBINotAuthorizedException error.

Follow the below steps to fix the issue:

Navigate back to the Home page. Click on the Workspaces tab from the left pane and then select your workspace from the list.
Choose the Manage Access option in the navbar.
When you click on Manage Access, you will be presented with a screen showing the current users and security groups having access to the workspace.
You can then click on Add people or groups so as to provide access.
After that, you will need to select Admin from the dropdown and add the user according to your requirements.
Now access for the workspace configuration is completed, select the report that you want to embed in a WordPress page or post.

This error "Your sign-in was successful but does not meet the criteria to access this resource" is usually due to some Conditional Access policy. In some cases, there may be certain account or system restrictions such as preinstalled certificates, token usb key, geographical location, etc... that will be needed to log in. The suggestion is to check with the administrator, for reference you can read the next article: Troubleshooting sign-in problems with Conditional Access - Microsoft Entra ID | Microsoft Learn

I hope this helps you.
