Power BI Embedded Using Masteruser Returns Operation returned an invalid status code 'Unauthorized'

[ColinChin]

Hi,

I am trying to do the Power Bi embedded using "Masteruser" from the https://github.com/microsoft/PowerBI-Developer-Samples/tree/master/.NET%20Core/Embed%20for%20your%20... sample application.

I have granted all permissions for my App Registrations in Azure AD. But when I run the application, it returns:

Operation returned an invalid status code 'Unauthorized'

at Microsoft.PowerBI.Api.EmbedTokenOperations.GenerateTokenWithHttpMessagesAsync(GenerateTokenRequestV2 requestParameters, Dictionary`2 customHeaders, CancellationToken cancellationToken)
at Microsoft.PowerBI.Api.EmbedTokenOperationsExtensions.GenerateTokenAsync(IEmbedTokenOperations operations, GenerateTokenRequestV2 requestParameters, CancellationToken cancellationToken)
at Microsoft.PowerBI.Api.EmbedTokenOperationsExtensions.GenerateToken(IEmbedTokenOperations operations, GenerateTokenRequestV2 requestParameters)
at AppOwnsData.Services.PbiEmbedService.GetEmbedToken(Guid reportId, IList`1 datasetIds, Guid targetWorkspaceId) in D:\Rassure\PBI\Embed for your customers\AppOwnsData\Services\PbiEmbedService.cs:line 167
at AppOwnsData.Services.PbiEmbedService.GetEmbedParams(Guid workspaceId, Guid reportId, Guid additionalDatasetId) in D:\Rassure\PBI\Embed for your customers\AppOwnsData\Services\PbiEmbedService.cs:line 75
at AppOwnsData.Controllers.EmbedInfoController.GetEmbedInfo() in D:\Rassure\PBI\Embed for your customers\AppOwnsData\Controllers\EmbedInfoController.cs:line 45

I am not sure if the error needs to be fixed from AD or Power BI side.

My appsettings.json has these settings:

{
  "AzureAd": {
    "AuthenticationMode": "MasterUser",
    "AuthorityUri": "https://login.microsoftonline.com/organizations/",
    "ClientId": "xxxxxxxxx-xxxxxx-xxxxxxxx-xxxxxxxxxxxxx",
    "TenantId": "",
    "Scope": [ "https://analysis.windows.net/powerbi/api/.default" ],
    "PbiUsername": "xxxxx@yyyyyy.zzz",
    "PbiPassword": "************",
    "ClientSecret": ""
  },
  "PowerBI": {
    "WorkspaceId": "xxxxxxxxx-yyyyy-tttt-zzzz-eeeeeeeee",
    "ReportId": "xxxxxxxx-xxxxxx-47a7-xxxxxxx-xxxxxxxxxxxxx"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*"
}

What else I am missing?

regards,

Colin

Hi @ColinChin ,

According to the error message, it seems that you havn't sufficient permission to the report. Please check if you add the related master user as a member or admin to the workspace. You can find the details in the following links.
