How to solve the problem for Telegram Bot CODE:400 (__init__.py:690 MainThread?

Question

Python

import telebot
import config

from telebot import types

client=telebot.TeleBot('///')
@client.message_handler(commands=['start'])

def welcome(message):
markup_inline = types.InlineKeyboardMarkup()

#Keyboard
markup = types.ReplyKeyboardMarkup(resize_keyboard=True)
item_yes = types.InlineKeyboardButton(text = 'Yes, I want', callback_data = 'yes')
item_no = types.InlineKeyboardButton('No, I don't want')

markup_inline.add(item_yes, item_no)

client .send_message(message.chat.id, 'Hello I want a bot to pass the test?',
reply_markup = markup_inline)

@client.callback_query_handler(func = lambda call: True)
def answer(call):
if call.data == 'yes':
client.send_message(message.chat.id, 'Food Image')
markup_reply = types.ReplyKeyboardMarkup(resize_keyboard = True)
item_1 = types.KeyboardButton('Evil')
item_11 = types. KeyboardButton('Right')

markup_reply.add(item_1, item_11)
client.send_message(call.message.chat.id, 'Select the correct answer',
reply_markup = markup_reply)

elif call.data == 'no':
client.send_message( message.chat.id, 'You're wondering why you don't want to take this test? More than 70% of people don't know what phishing is!')

@client.message_handler(content_types = ['text'])
def get_text(message) :
if message.text == 'Evil':
client.send_message(message.chat.id, 'Properly Down')
elif message.text == 'Right':
client.send_message(message.chat.id, 'THE Down Down')

client.polling(none_stop=True)

HERE the code itself does not work
