Image Feature Extraction API Error with PostMan (400 Bad Request)

Hi,

I try to test the ML Service for Image Feature Extraction

When I try with Postman, I get a 400 Bad Request Error :-/

{
    "_id": "6a02b7e0-b503-4c86-a4a4-3d1b1a2832a0",
    "error": "Invalid request",
    "error_description": "Service requires a list of (zipped) images.",

    },
