I made a telegram bot, it worked, but I restarted it, the same code that worked started to give an error. what to do?

Question

[Olenik23]

What should I do.
Here is the code:

import telebot
data = {}
TOKEN =  here is the bot token
bot = telebot.TeleBot(TOKEN)

def filter_echo(message):
    return data[message.chat.id]['state'] == 'echo'

@bot.message_handler(commands=['start'])
def start_message(message):
    data[message.chat.id]  = {'state':'start'}
    markup = telebot.types.InlineKeyboardMarkup()
    button_echo = telebot.types.InlineKeyboardButton('Эхо-бот',callback_data='echo')
    markup.add(button_echo)
    bot.send_message(message.chat.id,message.from_user.first_name + ' нажми на кнопку',reply_markup=markup)

    
@bot.callback_query_handler(func=lambda call: True)
def commands(call):
    bot.answer_callback_query(call.id)
    if call.data == 'echo':
        bot.send_message(call.message.chat.id, 'Напиши что-то')
        data[call.message.chat.id]['state'] = 'echo'


@bot.message_handler(func=filter_echo)
def echo_message(message):
    answer = message.text
    bot.reply_to(message,answer)

bot.polling(none_stop=True)

And here is the terminal output

what to do?

Translate your question at Russian. In spite of fact, that English is a main IT communication language, no one here is obliged to understand it.

Очевидно, что содержимое data сохранялось только в памяти и после рестарта бота было потеряно. Надо было сохранять куда-нибудь.
