Set cookies using flask-restx

Is there a way to set cookies using flask-restx? I'm using it in combination with flask-jwt-extended and I would like to have an endpoint that sets the jwt-cookie.

Here is what I've tried so far:

@namespace.route("/login")
class Login(Resource):
    @namespace.expect(login_model)
    def post(self):
        data = namespace.payload
        username = data.get("username")
        password = data.get("password")

        user = User.query.filter_by(username=username).first()
        if not user or not check_password_hash(user.password, password):
            return {"message": "Unauthorized"}, 401

        access_token = create_access_token(identity=user, fresh=True)

        response = jsonify()
        set_access_cookies(response, access_token)
        return response, 200

I get the following Error when sending a request to /login:

TypeError: Object of type Response is not JSON serializable

The code works as expected when switching out the response in the return value for a {}, so the problem seems to be that flask-restx doesn't support returning a Response directly.

I figured out what went wrong. When returning a Response directly, you must not add a status code. The resulting code looks like this:

@namespace.route("/login")
class Login(Resource):
    @namespace.expect(login_model)
    def post(self):
        data = namespace.payload
        username = data.get("username")
        password = data.get("password")

        user = User.query.filter_by(username=username).first()
        if not user or not check_password_hash(user.password, password):
            return {"message": "Unauthorized"}, 401

        access_token = create_access_token(identity=user, fresh=True)

        response = jsonify()
        set_access_cookies(response, access_token)
        return response
