Getting photo from Azure Active Directory to Power BI/Query

Hi!

I am trying to get data from Azure Active Directory to Power BI Desktop. I though that would be easy through the Active Directory Connector. But that wasn't easy. After spending to much time on that I come over using Azure AD Graph in stead. That seems to work and the graph explorer was helpful. 

https://graph.windows.net/{mytenant.Onmicrosoft.com}/users?api-version=1.6 gave me all users data. See code below. Take note of the field [email protected], it is a part of link to the picture. Adding https://graph.windows.net/{mytenant.Onmicrosoft.com}/ before this text we got a correct address to the picture. Then I though I could create this code below to get the picture perhaps as Base64 binary code, and hopefully could add this field in a chiclet slicer component or something to show the picture. The code below gave me an error

DataFormat.Error: We found extra characters at the end of JSON input.
Details:
Value=
Position=0

Perhaps it is a better way to get photos on power bi service/office365, but if any of you have a clue what is wrong and how to correct this I would be grateful

Regards Geir
