Hi

I have a simple bot that runs on pulling mode with the default number of threads(which is 2). I was looking for a more solid way to register my next_step_handlers and I stumbled upon RedisHandlerBackend and FileHandlerBackend.

I tried them both. by setting the next_step_backend when instantiating the bot. they both gave this error: TypeError: cannot pickle '_thread.lock' object

here is the complete stack:

I can't really investigate this issue. Check your code with examples and see if you are doing something wrong.

Sorry for the delay In response. I figured out that the problem was passing the "bot" object was the issue. It seems that Telebot object is not serializable.
