GenerateToken REST API returns 400 if I include customData

yp — Wed, 08 Aug 2018 09:14:50 GMT

Dear all,

I am developing a proof-of-concept Javascript app to test RLS with customdata (i.e., the app owns data scenario).

I have a model deployed on an on-premises Analysis Service server accessible through an on-premises gateway. Such a model is accessed by a PowerBI report (live connection) which is successfully published on a custom workspace (say "Workspace A") on app.powerbi.com. If I try to embed the report on the javascript app without specifying any custom data, I can succesfully get the embed token by POSTing to the ..../GenerateToken REST API, but if I try to specify any customData I get the following 400 error (redacted):

"error": {
      "code": "InvalidRequest",
      "message": "Dataset 3....e doesn't support providing CustomData in effective identity"
}

The api call is:

          `/groups/${workspaceId}/reports/${reportId}/GenerateToken`,
          {
            method: 'POST',
            data: {
              "accessLevel": "View",
              'identities': [
                {
                  username: "myusername",
                  customData: 'some string',
                  roles: ["examplerolename"],
                  datasets: ["report_dataset_id"],
                },
              ]
            }
          })

Does anyone know what I am doing wrong?

Thanks for your support!

Hi @yp,

I'm afraid the Custom Data isn't supported in your scenario. Please refer to the light blue note in this embedded-row-level-security#working-with-analysis-services-live-connections. If you want this feature, I would suggest you create an idea here.

>>>The CustomData feature will only work for models that reside in Azure Analysis Services, and it only works in live mode.

Best Regards,

Dale
