When using flask I try to send a patch request to update user data but get a TypeError message instead which I cant seem to figure out why.

Here’s the relevant part of my code…

class UpdateUser(Resource):
    def token_required(f):
        @wraps(f)
        def decorated_function(*args, **kwargs):
            token = request.headers.get('Authorization')
            if not token:
                return jsonify({'error': 'Token is missing!'}), 403
            try:
                token = token.split(" ")[1]  # Assuming 'Bearer <token>'
                data = jwt.decode(token, app.config['SECRET_KEY'], algorithms=['HS256'])
                return f(*args, **kwargs, current_user_id=data['sub'])
            except jwt.ExpiredSignatureError:
                return jsonify({'error': 'Token has expired!'}), 403
            except jwt.InvalidTokenError:
                return jsonify({'error': 'Invalid Token!'}), 403
        return decorated_function

    @token_required
    def patch(self, id, current_user_id):
        if id != current_user_id:
            return jsonify({'error': 'Unauthorized'}), 401

        user = User.query.filter_by(id=id).first()
        if not user:
            return jsonify({'error': 'User not found'}), 404

        data = request.get_json()
        if '_password_hash' in data:
            hashed_password = bcrypt.hashpw(data['_password_hash'].encode('utf-8'), bcrypt.gensalt()).decode('utf-8')
            user._password_hash = hashed_password

        for field in ['fname', 'lname', 'email', 'user_role']:
            if field in data:
                setattr(user, field, data[field])

        try:
            db.session.commit()
            user_dict = user.to_dict()
            return jsonify({'user': user_dict}), 200
        except Exception as e:
            db.session.rollback()
            app.logger.error(f"Error during updating user: {e}")
            return jsonify({'error': 'Internal Server Error'}), 500

api.add_resource(UpdateUser, '/user/<int:id>')

and i guess my model for good measure

class User(db.Model, SerializerMixin):
    __tablename__ = "users"

    id = db.Column(db.Integer, primary_key=True)
    fname = db.Column(db.String, nullable=False)
    lname = db.Column(db.String, nullable=False)
    email = db.Column(db.String, nullable=False, unique=True)
    user_role = db.Column(db.String, nullable=False)
    phone_number = db.Column(db.String, nullable=False)
    _password_hash = db.Column(db.String, nullable=False)

    reset_password_token = db.Column(db.String)
    reset_password_token_expiration = db.Column(db.DateTime)

    created_at = db.Column(db.DateTime, server_default=db.func.now())
    updated_at = db.Column(db.DateTime, onupdate=db.func.now())

    libraries = db.relationship('Library', backref='user')
    product_metrics = db.relationship('ProductMetric', backref='user')

    @property
    def password(self):
        return self._password_hash 

    @password.setter
    def password(self, password):
        self._password_hash = bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt()).decode('utf-8')

    def authenticate(self, password):
        return bcrypt.checkpw(password.encode('utf-8'), self._password_hash.encode('utf-8'))

    @validates('email')
    def validate_email(self, key, email):
        assert '@' in email, 'Invalid email address'
        return email

    def __repr__(self):
        return f"<User(id={self.id}, email='{self.email}')>"

    serialize_rules = ('-created_at', '-updated_at', '-libraries', '-product_metrics')

Edit: Here’s my full traceback error message
