Webhook not working on render.com

[nuson999]

I'm trying to run a telegram bot on render.com's web service.
Previously, I ran the same code on heroku, and it worked well.

POST requests can be seen in the logs of render.com, but the bot does not respond.
How can I make this work?

my app.py:

import os
from flask import Flask, request
import telebot

headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36"}

URL = "https://a-telegram-bot.onrender.com/"
TOKEN = "<Telegram Bot Token>" 

bot = telebot.TeleBot(TOKEN)
app = Flask(__name__)


@bot.message_handler(commands=['start'])
def start(message):
    bot.reply_to(message, 'Hello, ' + message.from_user.first_name)


# Webhook
@app.route('/' + TOKEN, methods=['POST'])
def getMessage():
    json_string = request.get_data().decode('utf-8')
    update = telebot.types.Update.de_json(json_string)
    bot.process_new_updates([update])
    return "!", 200


@app.route("/")
def webhook():
    bot.remove_webhook()
    bot.set_webhook(url=URL + TOKEN)
    return "!", 200


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=int(os.environ.get('PORT', 5000)))

Please enable debug logging and share all the logs so I could analyze more. Debug your code, which piece is not working?

These are the logs from render.com with debug logging enabled
I sent '/start' command twice.
