"UnknownError" when using Export-PowerBIReport cmdlet. Was working just fine a few days ago

[nikywilliams]

Anyone know what is going on here? This worked just fine a few days ago and now half my exports are failing with this message. All I see on here are "UnknownError", "WriteError", and "InternalServerError". Not sure where else to go here with troubleshooting especially since some other reports will export just fine. 

* I confirmed that C:\tmp exists

* This is scripted so it uses the GUIDs gathered from the API, I know the GUIDs are correct.

* As mentioned, this was working a few days ago

* About half the reports will export just fine

* Using the online PBI REST API tool also yields a similar "UnknownError", this also was working earlier. (https://docs.microsoft.com/en-us/rest/api/power-bi/reports/export-report)

Any direction is very appreciated, I'm stumped!

Thank you for your response.

Please see the image in the original post, "Resolve-PowerBIError" was executed right after the "Export-PowerBIReport" cmdlet failed. I was unable to find any meaningful information.

On another note. I just tried the exact same command again this morning (see image below) and it worked. No error, no issue. Does anyone have any idea why it would work one day then not the next?? This makes it very difficult to create any sort of consistent automated process.

Can you try this cmdlet to see if it gives you more information about failure? https://docs.microsoft.com/en-us/powershell/module/MicrosoftPowerBIMgmt.Profile/Resolve-PowerBIError...
