I have a html page where i have some forms where i write the crust, size and flavor of a pizza. I try to get those data via request.form, but i get the error

'werkzeug.exceptions.BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.'

I searched for it and most people would say it is because the form would be missing, or not maching the name. But i guess it is.

from flask import Flask, render_template, request, redirect
from flask_sqlalchemy import SQLAlchemy
from datetime import datetime

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///pizza.db'
db = SQLAlchemy(app)

class Order(db.Model):
    order_id = db.Column(db.Integer, primary_key=True)
    crust = db.Column(db.String(80), unique=True, nullable=False)
    flavor = db.Column(db.String(120), unique=True, nullable=False)
    size = db.Column(db.String(120), unique=True, nullable=False)
    timestamp = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)

    def __repr__(self):
        return '<Pedido %r>' % self.order_id

@app.route('/', methods=['POST', 'GET'])
def index():
    if request.method == 'GET':
        return render_template('index.html')
    elif request.method == 'POST':
        flavor = request.form['flavor']
        size = request.form['size']
        crust = request.form['crust']
        new_order = Order(crust=crust, flavor=flavor, size=size)
        try:
            db.session.add(new_order)
            db.session.commit()
            return redirect('/')
        except:
            return 'error posting data...'
        
if __name__=="__main__":
    app.run(debug=True)
