The bot crashes when people write to it

Question

The bot crashes when it receives any message that is not related to pressing a button, I tried to fix it through ChatGPT by adding a function that when the bot receives a message, it responds "use the menu below", but this did not help with crashes.

I need the bot to respond only to buttons and when it is written an arbitrary message it responds so that the user uses the menu

Here is the code:

import telebot
from telebot import types
import requests
import config

bot = telebot.TeleBot(config.token)

# Define the API key
api_key = 'API_KEY'  # Replace 'your_api_key' with your actual API key

@bot.message_handler(commands=['start'])
def start(message):
    markup = types.ReplyKeyboardMarkup(resize_keyboard=True)
    btn1 = types.KeyboardButton(" Say hello")
    btn2 = types.KeyboardButton("❓ Ask a question")
    markup.add(btn1, btn2)
    bot.send_message(message.chat.id, text="Hello", reply_markup=markup)

@bot.message_handler(content_types=['text'])
def func(message):
    if message.text == " Say hello":
        bot.send_message(message.chat.id, text="Hi, thanks for reading the article!)")
    elif message.text == "❓ Ask a question":
        markup = types.ReplyKeyboardMarkup(resize_keyboard=True)
        btn1 = types.KeyboardButton("What's my name?")
        btn2 = types.KeyboardButton("What can I do?")
        back = types.KeyboardButton("Back to main menu")
        markup.add(btn1, btn2, back)
        bot.send_message(message.chat.id, text="Ask me a question", reply_markup=markup)
    elif message.text == "What's my name?":
        bot.send_message(message.chat.id, "I don't have a name.")
    elif message.text == "What can I do?":
        bot.send_message(message.chat.id, text="Say hello to the readers")
    elif message.text == "Back to main menu":
        markup = types.ReplyKeyboardMarkup(resize_keyboard=True)
        button1 = types.KeyboardButton(" Say hello")
        button2 = types.KeyboardButton("❓ Ask a question")
        markup.add(button1, button2)
        bot.send_message(message.chat.id, text="You have returned to the main menu", reply_markup=markup)
    else:
        # Handle messages that don't relate to pressing the buttons
        bot.send_message(message.chat.id, text="Use the menu buttons")

        # Example of making an API request with the API key
        api_url = 'https://api.example.com'  # Replace with the actual API endpoint
        headers = {'Authorization': 'Bearer ' + api_key}
        response = requests.get(api_url, headers=headers)

        if response.status_code == 200:
            # Process the API response
            data = response.json()
            bot.send_message(message.chat.id, text=f"API Response: {data}")
        else:
            bot.send_message(message.chat.id, text="Error accessing the API")

bot.polling(none_stop=True)

I tried to fix it through ChatGPT by adding a function that when the bot receives a message, it responds "use the menu below", but this did not help with crashes.

Answer 1

When I run your code and send a simple message to the bot, the following error is shown:

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='api.example.com', port=443): Max retries exceeded with url: / (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x10d3cc5d0>: Failed to resolve 'api.example.com' ([Errno 8] nodename nor servname provided, or not known)"))

The else case of the content_types=['text'] triggers when you send such a simple message.

The error throws because the request to example.com fails. Seem like you didn't include any error checking on that request.

Consider reading/implementing the following:
