Error using Invoke-PowerBIRestMethod using a service principal

Hello Community,

I followed the steps below to use the powershell Invoke-PowerBIRestMethod using a service principal but facing errors getting the details of the group or dataset.

I followed the below steps:

- Created a service principal in Azure AD

- Assigned permissons per screenshot below

- Able to login using service principal details using Connect-PowerBIServiceAccount successfully

- Added service principal as Admin to the Power BI workspace

- Enabled the setting "Allow service principals to use read-only power bi admins APIs" in the power bi admin portal

- Added the Service Principal to the correct AD Group

- Then tried to run Invoke-PowerBIRestMethod -Url 'groups' -Method Get

Then I get the error below:

Invoke-PowerBIRestMethod : One or more errors occurred.
+ Invoke-PowerBIRestMethod -Url 'https://app.powerbi.com/v1.0/myTenantId/groups' -Method Get

- Am I missing additional permissions on the service principal?

- Do I need power bi enterprise admin rights?

- Any typos or stuff I have missed?

I checked the other posts on this topic before posting here but they did not help resolve my issue 🙂

Your help is appreciated!
