Error processing JSON?

Question

Python

I use WebHook in my TelegramBot
. It has, let's say, a form (name and phone number)

So, when filling in the `name`, an error occurs:

2019-02-01 13:06:42,362: Exception on /`secret` [POST]
Traceback (most recent call last):

Here is the part of the code where the error occurs:

@app.route('/{}'.format(secret),methods=['POST'])
def webhook():
  print(flask.request.headers)
  if flask.request.headers.get('content-type') == 'application/json':
    json_string = flask.request.get_data().decode('utf-8')
    update = telebot.types.Update.de_json(json_string)
    bot.process_new_updates([update])
    return ''
  else:
      print('You NOT made it!')
      flask.abort(403)

Answer 1

Most likely, you named an attribute of a class (most of all task), just like a method of it.

Answer 2

Exception on /`secret` [POST]
No error in url?

Answer 3

Judging by the place where the error occurs in your liseners line(s), but there should be a method(s)
def handle_messages(messages):
for message in messages:
# Do something with the message
bot.reply_to(message, 'Hi')
bot .set_update_listener(handle_messages)
