Can you please help me solving this error?

{
    "code": "PrincipalNotExists",
    "message": "The request cannot be completed because the principal in tenant ***************************** with object id c17b22cc-************** does not exist."
}

Invoking this API: https://api.powerplatform.com/environmentmanagement/environments?api-version=2024-10-01

The AppRegistration does exists and it is configured as shown

As usual a TOken is being requested to Azure:

then used to make the api call.

Has the Service Principal been added to the Dataverse environment with proper permissions?

Go to https://admin.powerplatform.com > Manage > Environments > S2S Apps > Add Principle and assign a security role

If I understood well what you suggest would allow to access the environment where the app reg is being configured, but what I need is to get details about all envirnoments in power platform

Sorry about that, thought this was for a specific environment.

I did find this article where it looks like you need to register the Service Principle with Power Platform through the API. Was that done after creating the Service Principal?
