Keep getting the same message from messenger

[sameerkumar16]

fbmessenger version 5.0.0
I am using Rasa-core which uses the fbmessenger as facebook connector, Issue is when my bot takes long time to respond which usually happens when some API is being called I start getting the same message back from messenger no mattter what is being typed by user .So I searched a bit and I came to this conclusion that facebook sends the same message when it doesn't get a response in few seconds .OR it may be due to my localtunnel being patchy.

Try using threading concept. This will do the processing as a different thread so the process will not take long time to respond.
