Rest API Export Report to PDF that uses Azure Analysis Service as a data set

Hi;

    Just an update on the solution.

    It seems to pass the effective identity one needs to add the following into the body :

{

    "format": "pdf",

    "powerBIReportConfiguration": {

        "identities": [

            {

                "username": "{ ServicePrincipal Object ID }",

                "roles": [

                    "{Role in AAS}"

                ],

                "datasets": [

                    "{datasetID}"

                ]

            }

        ]

    }

}

*Just also note as per the MS documentation that one needs to pass in the Service Principal object id and not the service ServicePrincipal app id
