During the conversation if response takes longer time(30 secs) chatbot just responds with thumbs up/down message. nothing else.

The payload names no repository files, tests, or entry points. Start by reproducing the uploaded-document flow with a response taking more than 30 seconds and inspect the Lex session response; done means the chatbot no longer ends with only thumbs-up/down feedback when processing exceeds that interval.
