Expected 'None' but got CognitiveServicesCredentials Instead plus InvalidResponse

• Package Name: azure face recognition
• Package Version: latest
• Operating System: Ubuntu 20.04 LTS
• Python Version: python3.8

Describe the bug I'm setting up a code for face recognition and when I'm making the code I get this warning while I implement the face client. face_client = FaceClient(ENDPOINT, CREDENTIALS)

After this there's this other error which causes the code to break.

response_faces = face_client.face.detect_with_stream(
    image=open(image, 'rb'),
    detection_model='detection_03',
    recognition_model='recognition_04',
    return_face_landmarks=True,
)

This is how I wanna send messages locally by stream but the problem is that whenever I run this code I get this problem:

/home/thecowmilk/dev/azure_faceapi/venv/bin/python /home/thecowmilk/dev/azure_faceapi/faceapi/starting.py
Traceback (most recent call last):
  File "/home/thecowmilk/dev/azure_faceapi/faceapi/starting.py", line 17, in <module>
    response_faces = face_client.face.detect_with_stream(
  File "/home/thecowmilk/dev/azure_faceapi/venv/lib/python3.8/site-packages/azure/cognitiveservices/vision/face/operations/_face_operations.py", line 782, in detect_with_stream
    raise models.APIErrorException(self._deserialize, response)
azure.cognitiveservices.vision.face.models._models_py3.APIErrorException: (InvalidRequest) Invalid request has been sent.

To Reproduce Steps to reproduce the behavior:

1. A clean install of your OS
2. install these libraries:

   azure-cognitiveservices-vision-face
   azure-cognitiveservices-vision-computervision
   azure-cognitiveservices-vision-customvision
   azure-cognitiveservices-formrecognizer
   pillow
   pandas

3. Write this code:

   
   import os
   import io
   import cv2
   from azure.cognitiveservices.vision.face import FaceClient
   from azure.cognitiveservices.vision.face.operations import FaceOperations
   from msrest.authentication import CognitiveServicesCredentials
   from PIL import Image, ImageDraw, ImageFont

API_KEY = 'your_free_sub_api_key' ENDPOINT = 'your_free_sub_endpoit'' CREDENTIALS = CognitiveServicesCredentials(API_KEY) image = 'realmadrid.jpg' face_client = FaceClient(ENDPOINT, CREDENTIALS) operations = FaceOperations

response_faces = face_client.face.detect_with_stream( image=open(image, 'rb'), detection_model='detection_03', recognition_model='recognition_04', return_face_landmarks=True, )

if not response_faces: raise Exception("No face detected!")

print(f"Number of face detected {len(response_faces)}")

4. Try to run and then you have got the idea of this error

**Expected behavior**
It should have worked an returned a result

Thank you for your feedback. This has been routed to the support team for assistance.

@thecowmilk We are looking into it and get back to you for any additional information.

[SaurabhSharma-MSFT]

@thecowmilk I do not see any issues calling detect_with_stream function with both results and no results. See below -

Which version of the vision face library you are using?

Thanks Saurabh

@SaurabhSharma-MSFT I debugged a little and I got this response back

raise DeserializationError("Cannot deserialize as [{}] an object of type {}".format(
azure.core.exceptions.DeserializationError: ("Unable to deserialize response data. Data: {'error': {'code': 'InvalidRequest', 'message': 'Invalid request has been sent.', 'innererror': {'code': 'UnsupportedFeature', 'message': 'Feature is not supported. Please apply for access at https://aka.ms/facerecognition'}}}, [DetectedFace], DeserializationError: Cannot deserialize as [DetectedFace] an object of type <class 'dict'>", DeserializationError("Cannot deserialize as [DetectedFace] an object of type <class 'dict'>"))

I don't know if it intended or not.... Also when I do send the requests with my own API Key it is forbidden for me, it return a 403. What am I doing wrong?

[SaurabhSharma-MSFT]

@thecowmilk This is intended as Face API falls under Limited Access features for Cognitive Services. You got this error since what you are trying to call is now limited access to them because you have not been approved to use that capability. Face service is only available to Microsoft managed customers and partners. Please use the Face Recognition intake form to apply for access- aka.ms/facerecognition. Please let me know if you have any questions. Thanks
