Hello @v-mengzhu-msft ,

 

My Azure function is failing sometimes and I am not able to understand the reason behind this.

 

The execution flow of the Azure function is shown as below:

GetAccessToken -> CreatePowerBIClient -> ExportPowerBIReports


When I checked the logs of my Azure function, It is containing few failures.

Exception: System.AggregateException
Message: One or more errors occurred. (An error occurred while sending the request.)

This Exception is occuring exactly when I called "clientApp.AcquireTokenForClient(scopes).ExecuteAsync().Result" to get Azure AD token for service principal

 

In some other cases, I am getting the below exception message when trying to retrieve the PowerBIReports using PowerBIClient

" Client.Reports.GetReportsAsync"

Exception: TaskCanceledException

Message: The operation was canceled.

I would like to know if there is any issue with Power BI client in .NET
