InternalServerError when calling ExportReportInGroupAsync

[_TJ]

Since yesterday morning, my C# code to download reports from the service, stopped working after running daily for more than a year. The error I receive is not giving my any details. The ExportReportInGroupAsync is throwing 'InternalServerError'.

I've migrated from V2 to the latest 'standard' nuget package Microsoft.PowerBI.Api, but I got the same error.

Anyone know where to look for? 

Error, Microsoft.Rest.HttpOperationException: Operation returned an invalid status code 'InternalServerError'

Hi @Anonymous 

- for three days, it wasn't working

- then, all of a sudden, it worked again, without any changes made 

- now it stopped again, since yesterday

I have no clue where to look for. No changes were made to the report, only 'regular' increase of data due to refreshes.

Hi @_TJ ,

Whether the problem still persist? Has anyone made any change to these related reports? 

Best Regards
