Rocket Chat Hubot Adapter is not replying back

问题

Hi i am running hubot with rocket chat. I have created another user "mybot" having bot role and used it and got connected successfully.

Below are my environment variables

export ROCKETCHAT_ROOM=''
export LISTEN_ON_ALL_PUBLIC=true
export ROCKETCHAT_USER=mybot
export ROCKETCHAT_PASSWORD=123456789
export ROCKETCHAT_AUTH=password

Hubot is not responding back to me when i am sending any message.

Messages send are visible in terminal logs but a return message is not shown from the hubot.

Screenshot of terminal
