passing bearer access token to auth fails about powerbi-jupyter

[bapat-atharva]

Hi @Cagataydemirkol,

This approach you are using is used for App Owns Data. With this access-token you will be able to generate embed tokens using the PBI Rest APIs. But embed-tokens are not supported currently in powerbi-jupyter.

You could use master-user approach and specify a username(email) and password in the request with grant_type as 'password'. With this access token you should be able to embed any of the reports.

@bapat-atharva our organization will not allow master user. Our only option is Service Principal for authentication. The service principal has member role in powerbi the workspace of report and dataset.
I am trying to download data from PowerBI visuals programmatically by running code in Google Cloud Function.

def get_powerbi_access_token(secrets: dict, scopes: list =None):
    from msal import ConfidentialClientApplication
    client_id = secrets['client_id']
    client_secret = secrets['client_secret']
    tenant_id = secrets['tenent_id']
    authority_url = f'https://login.microsoftonline.com/{tenant_id}'
    
    app = ConfidentialClientApplication(client_id,client_credential=client_secret,authority=authority_url)
    if not scopes:
        scopes = ['https://analysis.windows.net/powerbi/api/.default']
        
    return app.acquire_token_for_client(scopes=scopes)

access_token = get_powerbi_access_token(secrets)['access_token']
report = Report(group_id=group_id, report_id=report_id, auth=access_token)
report

It is throwing below error while running in notebook

Will this approach work to automate data export from powerbi reports to excel using functions on Azure or GCP?
