Microsoft Cognitive Services - Face API

    Question

  • I'm getting an unhandled exception in my code when calling the Face API.  see below for the output.  Any help would be appreciated.  I can see in the Azure portal the the call was blocked, but I don't know why.

    Thanks in advance,

    -Matt
