422 unprocessable entity fastapi when trying to call api to get image

I am a newbie to fastAPI. While I tried to write an API to get the uploaded image I got this error: INFO: 127.0.0.1:50702 - “POST /faces/identify HTTP/1.1” 422 Unprocessable Entity

my codes here. It very thankful if someone can help

router = APIRouter()
# Identify faces on the image
@router.post('/faces/identify')
async def web_recognize(file_upload: UploadFile = File(...)):
    face_recognition_service = faceRecognition.FaceRecognition_service(faces_dict)
    file = face_recognition_service.extract_image(file_upload)
    if file and face_recognition_service.is_picture(file.filename):

        return face_recognition_service.detect_faces_in_image(file)
    else:
        raise ErrorResponse(code=codes.code_files_invalid, message=messages.message_files_invalid, `status=status.HTTP_400_BAD_REQUEST)`

A response having status code 422 will have a response body that specifies the error message, please have a look at that. Also please mention from where are you making the request.

Below example code should work

import requests
url = "http://localhost/faces/identify"
files = {'file_upload': open('test.jpg', 'rb')}
requests.post(url, files=files)

Basically, you will have to make a POST request having content-type: multipart/form-data

Dear here is my response { "detail": [ { "loc": [ "body", "image" ], "msg": "field required", "type": "value_error.missing" } ] }

and here is my curl in postman curl --location --request POST 'http://localhost:8080/faces/identify' \ --form 'file=@"1.jpg"'

where the image is in working directory. I just put it there to test my api
