I don’t know the answer to your question, but am sending up the bat signal to @samaguire , who is extremely knowledgeable about PowerShell and I’m confident will know how to resolve this.
Thank you so much. I googled before posting but could not find any clue and it was my first time with Power shell, so I thought I might be missing something. I was just about to check .Net & Powershell version etc and you saved a lot of my time.
It might be issue of some upgrade. Do you know if we can downgrade MicrosoftPowerBIMgmt to test?
Thank you so much for your support. I followed these steps and tried different versions but got same error. I believe it is an issue where tenants might be in Germany cloud for MS power BI.
As you pointed out, I was not only one and this issue was related to MS. Today, I checked and I am able to connect to Power BI service using Powershell. Thanks heaps for your support.
