Getting error when calling Power BI Embed Report Export To PDF API

[MehboobAhmad]

We are using Power BI c# SDK to export Power BI report in PDF.
We setup app registration in Azure Active Directory and assigned the required permissions. We Have power-bi-embedded A4 Plan
Some time pdf is generated and some time its not.
When its not generated, following error is thrown:
"Operation returned an invalid status code 'Forbidden'".

Code

var tenantSpecificURL = this.PowerBIConfig.AuthorityUrl.Replace("common", this.PowerBIConfig.TenantId, StringComparison.InvariantCultureIgnoreCase);
var authenticationContext = new AuthenticationContext(tenantSpecificURL);
var credential = new Microsoft.IdentityModel.Clients.ActiveDirectory.ClientCredential(this.PowerBIConfig.ApplicationId, this.PowerBIConfig.ApplicationSecret);
var authenticationResult = await authenticationContext.AcquireTokenAsync(this.PowerBIConfig.ResourceUrl, credential).ConfigureAwait(false);

var tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");
PowerBIClient pbiClient = new PowerBIClient(new Uri(this.PowerBIConfig.ApiUrl), tokenCredentials);
Export export = pbiClient.Reports.ExportToFileInGroup(new Guid(this.PowerBIConfig.WorkspaceId), new Guid(reportID), exportRequest);
string exportId = export.Id;
do
{
export = pbiClient.Reports.GetExportToFileStatusInGroup(new Guid(this.PowerBIConfig.WorkspaceId), new Guid(reportID), exportId);
Console.WriteLine(" - Export status: " + export.PercentComplete.ToString() + "% complete");
}
while (export.Status != ExportState.Succeeded && export.Status != ExportState.Failed);

if (export.Status == ExportState.Failed)
{
Console.WriteLine("Export failed!");
}

@AmosHersch  responce error massage

This looks like the exception when the error is returned, what I meant is the Http response message itself, it has headers and body. Maybe you can capture using Fiddler or other tool. Without the response message I can't help much

Hi @MehboobAhmad ,

Do you mean that the call to the "Export to File" API returns Forbidden?

Did you check to see if the response body has additional information for the reason of the Forbidden status?

If the response body is empty or doesn't help with understanding the issue you can reply here with the request ID from the response headers and I might be able to find the reason.
