Update dispatcher loses the reference to chat_id #32

Closed MattiaFailla closed 3 years ago

MattiaFailla commented 3 years ago

The dispatcher seems to lose the chat id attribute in some edge cases.

This lead to a process termination.

The issue seems to be related with ".message" and it's way to handle the update_message method.

I've disabled the antiflood module, since there may be an issue with the flood counter and the update_message method

MattiaFailla commented 3 years ago

A fix has been implemented in the following commit: 8da0575e55e74a18ac74222bda30edde4d573248

It seems that Telegram is sending us invalid update json data perhaps due to a network problem or a forced closure of the session. The fix simply ignore this error and the bot waits for the next update.
