Embed Token API Error: Creating embed token with multiple identities is not supported

[pbimdland]

Hello everyone,

I am creating a dashboard in a web application via App Owns Data. I am able to follow this guide and embed my dashboard to the web application: https://docs.microsoft.com/en-us/power-bi/developer/embed-sample-for-customers

Also, I am trying to implement Row-Level Security via the REST API as mentioned in this guide: https://docs.microsoft.com/en-us/power-bi/developer/embedded-row-level-security

However, the REST API gives me the following error message as the response:

{'error': {'code': 'InvalidRequest', 'message': 'Creating embed token with multiple identities is not supported'}}

I am using almost the same payload (see below) as the one mentioned in the guide, and if I comment-out identities, I get the embed token as normal.

{
    "accessLevel": "View",
    "identities": [
        {
            "username": "EffectiveIdentity",
            "roles": [ "Role1", "Role2" ],
            "datasets": [ "fe0a1aeb-f6a4-4b27-a2d3-b5df3bb28bdc" ]
        }
    ]
}

Any ideas why I'm getting this error message? Thanks.

Hi,

I got the same error and contacted the Microsoft Power BI support team and they helped me out. Turns out there was something wrong with my request.

I'm creating an App owns data web application in Python Django and this is what works for me. 

import requests
import json

username = '...'
password = '...'
client_id = '...'
report_id = '...'
group_id = '...'
dataset_id = '...'
settings = {
            "accessLevel": "View",
            "identities": [
                {
                "username": "Andrew Ma",
                "roles": [ "Manager" ],
                "datasets": [ dataset_id ]
                }
            ]
        }

data = {
    'grant_type': 'password',
    'scope': 'openid',
    'resource': r'https://analysis.windows.net/powerbi/api',
    'client_id': client_id,
    'username': username,
    'password': password
}
# Get access token
response = requests.post('https://login.microsoftonline.com/common/oauth2/token', data=data)
print(response.content)
access_token = response.json().get('access_token')

# Get embed token
dest = 'https://api.powerbi.com/v1.0/myorg/groups/' + group_id \
    + '/reports/' + report_id + '/GenerateToken'
embed_url = 'https://app.powerbi.com/reportEmbed?reportId=' \
    + report_id + '&groupId=' + group_id
headers = {'Authorization': 'Bearer ' + access_token, 'Content-Type': 'application/json'}
response = requests.post(dest, json=settings, headers=headers)
print(response.content)
embed_token = response.json().get('token')
print(embed_token)

Turns out I forgot to add the Content-Type: application/json to the request headers. Also, my settings weren't formatted as json in the request.

Hope this helps you out.

Regards

Nobody at Microsoft knows what this error means?
