CS50 Final Project Strange Syntax Error

Question

I am making a web app for my final project. In my code, a strange syntax error is occurring in the middle of a SQL query. Please, may somebody help?

Code for that route (problematic line is surrounded by stars):

@app.route("/users/edit", methods=["GET", "POST"])
@login_required

    id = session['user_id']
    introle = int(db.execute("SELECT role FROM users WHERE userId = :id;", id=id)[0]['role'])

        role = 'admin'
    elif introle == '2':
        role = 'engineer'
    if request.method == "GET":
        admin = db.execute("SELECT userName FROM users WHERE role = 1;")

Answer 1

You should check the line before. Are all the open/close balanced? (My sources say no :)
