(400) Bad Request : MS Defender Connection

Dear Community, 

I am quite new to PowerBI .

I am trying to use a Microsoft shared MS Defender report  (https://github.com/Azure/Azure-Sentinel/tree/master/Tools/MDO%20Power%20BI%20Dashboard#how-to-use-the-pbit-file)  

We are an MS Defender Customer and I have PowerBI Pro license . 

The problem is that when I open the report in PowerBI Desktop, I receive the following error for every table that the report is using i.e. :

Web.Contents failed to get contents from 'https://api.security.microsoft.com/api/advancedhunting/?key=EmailEvents%20%7C%20where%20Timestamp%20%3Eago(30d)%20%7C%20where%20isnotempty(ThreatTypes)%20%7C%20summarize%20count()%20by%20SenderFromDomain,%20bin(Timestamp,%201d)%20%7C%20sort%20by%20count_%20%20%7C%20take%2015' (400): Bad Request

I suspect that it has to do something with the MS Defender Schema...anyway ideas or how to correct it or how to troubleshoot ?

Does the PowerBI Desktop has any more detailed debug logs ?
