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.",
    "processed_time": "Fri, 14 Jul 2017 07:15:32 GMT",
    "request": {
        "files": null,
        "options": {},
        "tenantName": "imgclassif-tech-user",
        "texts": []
    },
    "status": "FAILED",
    "status_code": 400,

    Hello Markus Reich

    Did you resolve this? I faced a problem with the ML API as well and I'm looking for a resolution.

    Hi Markus Reich,

    In help document of SAP, Image Feature Extraction is capable of extracting feature vectors for any given image which can be used for comparison, informational retrieval, clustering or further processing. When I try to run the API, I get a lot of feature_vector data, do you know how to use them to compare between different files?

    Regards,

    Hi all,

    To call the Image Feature Extraction API with Postman, simply do as below:
    1.Only add APIKey to the headers. No other header needed.

    2.In the body, select form-data, add a key named "files" as file type, and then choose your target images
