Token always return invalid flask

Question

I'm making a website application using flask as the backend and angular as the frontend, when I login I use token based with jwt but every time I call the token_required decorator it always returns "a valid token is missing" can anyone help me?

@app.route('/login', methods=['POST'])
def login_post():
    if request.method == 'POST':
        try:
            login_data = request.get_json()
            email =  login_data['email']
            password = login_data['password']
            user = User.query.filter_by(email=email).first()
            if user and check_password_hash(user.password, password):
                token = jwt.encode(
                    {'public_id' : user.public_id, 'exp' : datetime.datetime.utcnow() + datetime.timedelta(minutes=45)}, 
                    app.config['SECRET_KEY'])
                login_user(user)
                return jsonify({'token' : token}),200

        except Exception as ex:
            print(str(ex))
            return jsonify({'message': 'invalid respond'}), 422


def token_required(f):
   @wraps(f)
   def decorator(*args, **kwargs):
       token = None
       if 'x-access-tokens' in request.headers:
           token = request.headers['x-access-tokens']
 
       if not token:
           return jsonify({'message': 'a valid token is missing'})
       try:
           data = jwt.decode(token, app.config['SECRET_KEY'])
           current_user = User.query.filter_by(public_id=data['public_id']).first()
       except:
           return jsonify({'message': 'token is invalid'})
 
       return f(current_user, *args, **kwargs)
   return decorator

i use this method to test the token

@app.route('/user', methods=['GET'])
@token_required
def authenticatedUser():
    return jsonify("OK");
