Unable to Connect Power BI Desktop to OMS Log Analytics with Blank Query and Organizational Signon

[kchase04]

When attempting to use a Blank Query in Power BI desktop to connect to a query in OMS I recieve the below error when I attempt to sign in using an organizational account. I never receive an Azure login prompt. Any help would be greatly appreciated.

The WWW-Authenticate header doesn't contain a valid authorization URI. Header value: '[object Object]'.

Hi @kchase04,

I noticed that some other users also encountered this problem several days ago. Currently, the issue should be fixed. Please test again in your environment.

I was able to fix the issue by performing a repair on the installation.

Just started seeing this error as well.  It only started happening since I upgraded to the Nov 2017 update, not sure if it is related to the problem though.
