how to set up "Flask" webhook for "telebot"? - python-3.x

Question

Locally everything works, with the help of "ngrok" I hang up a webhook. I uploaded the code to "pythonanywhere" and the handlers are idle.
There is such a view for Flask
#app.route("/", methods=["GET", "POST"])
def receive_update():
if request.headers.get("content-type") == "application/json":
json_string = request.get_data().decode("utf-8")
update = telebot.types.Update.de_json(json_string)
bot.process_new_updates
return ""
else:
abort(403)
telegram sends updates to the server, but I'm confused by the presence of such entities
<telebot.types.User object at 0x7fc907fb8b0>,
instead of key: valueю
