python - Flask: Firebase orderBy must be a valid JSON encoded path

Question

I use Flask and Firebase.

I push some values to the database and i want to get for example some data which its id=1 . So , i want to write some Complex Queries.

Heres my app.route :

@app.route('/satis', methods=['GET', 'POST'])
def satis():
    if (request.method == 'POST'):
        users_by_score = db.child("names").order_by_child("id").equal_to(2).get()
        us=users_by_score
        return render_template('satis.html', u=us.val())
    return render_template('satis.html')

Heres is index.html

<div class="container-fluid">
        {% for l in u %}
            <ul class="list-group">
                <li class="list-group-item">
                    <h4>{{l}}</h4>
                </li>
            </ul>
        {% endfor %}
    </div>

And this is the error :

 "error" : "orderBy must be a valid JSON encoded path"

This is my Firebase Real Time Database :
