process_new_updates() doesn't work when its fed the updates list got from get_updates()

[CarlosBueno99]

Please answer these questions before submitting your issue. Thanks!

1. What version of pyTelegramBotAPI are you using? % pip freeze | grep pyTelegramBotAPI pyTelegramBotAPI==4.16.1

2. What OS are you using? macOS 14.3.1 on MacBook Air m2

3. What version of python are you using? 3.12.2

Here's an example of my test script:

@bot.message_handler(commands=['start', 'hello'])
def send_welcome(message):
    bot.reply_to(message, "Howdy, how are you doing?")

@bot.message_handler(func=lambda message: True)
def echo_message(message):
    bot.reply_to(message, message.text)

print(bot.get_me().first_name)

updates_list = bot.get_updates()
print("type of the update list returned by bot.get_updates():",type(updates_list))

print('type of each update in the list')
for update in updates_list:
    print(type(update), update.update_id)

bot.process_new_updates(updates_list)

Here's the output when I run that file:

BuenoBotTest
type of the update list returned by bot.get_updates(): <class 'list'>
type of each update in the list
<class 'telebot.types.Update'> 862015394
<class 'telebot.types.Update'> 862015395
<class 'telebot.types.Update'> 862015396
<class 'telebot.types.Update'> 862015397
<class 'telebot.types.Update'> 862015398
<class 'telebot.types.Update'> 862015399

Everything works fine if I use bot.infinity_polling() instead.

What do you mean under "doesn't work"?

[CarlosBueno99]

it exits the program as if it ran as expected... but none of the updates are handled and none of the messages are replied on the Telegram conversation.

maybe there is a reason for that.

I checked. Set "threaded" to False and it will work.

bot = telebot.TeleBot("xxx", threaded=False)
