Cannot signin using django boilerplate

What stack are you using?

(ex: MERN(mongoose + react), DR(django + react), PEN, etc.)

What's the problem you're trying to solve?

/sign-in/ post is not working

Post any code you think might be relevant (one fenced block per file)

class SignIn(generics.CreateAPIView):
    # Override the authentication/permissions classes so this endpoint
    # is not authenticated & we don't need any permissions to access it.
    authentication_classes = ()
    permission_classes = ()

    # Serializer classes are required for endpoints that create data
    serializer_class = UserSerializer

    def post(self, request):
        creds = request.data['credentials']
        print(creds)
        # We can pass our email and password along with the request to the
        # `authenticate` method. If we had used the default user, we would need
        # to send the `username` instead of `email`.
        user = authenticate(request, email=creds['email'], password=creds['password'])
        # Is our user is successfully authenticated...
        if user is not None:
            # And they're active...
            if user.is_active:
                # Log them in!
                login(request, user)
                # Finally, return a response with the user's token
                return Response({
                    'user': {
                        'id': user.id,
                        'email': user.email,
                        'token': user.get_auth_token()
                    }
                })
            else:
                return Response({ 'msg': 'The account is inactive.' }, status=status.HTTP_400_BAD_REQUEST)
        else:
            return Response({ 'msg': 'The username and/or password is incorrect.' }, status=status.HTTP_422_UNPROCESSABLE_ENTITY)

If you see an error message, post it here. If you don't, what unexpected behavior are you seeing?

MultiValueDictKeyError at /sign-in/

What is your best guess as to the source of the problem?

Originally, I thought that it was related to not having a page to show successful login, but then I looked into the code and it says that it should return the login creds & token or a specific error message, but I am not seeing either one of those..

What things have you already tried to solve the problem?

tested it in Postman and it is working Googling and stack overflow
