chatops.post_message crashes st2chatops using Rocket.Chat

[MrDiba]

SUMMARY

Manually triggering chatops.post_message results in a crash of st2chatops using Rocket.Chat.

STACKSTORM VERSION

$ st2 --version
st2 3.4.1, on Python 3.6.9

$ cat /etc/os-release 
NAME="Ubuntu"
VERSION="18.04.5 LTS (Bionic Beaver)"
...

installed using the following command:
bash <(curl -sSL https://stackstorm.com/packages/install.sh) --user=st2admin --password=Ch@ngeMe --version=3.4.1

Steps to reproduce the problem

1. Install StackStorm on a clean VM. (I'm using StackStorm version 3.4.1 because of Docker st2chatops will not start rocketchat adapter #167)
2. Configure st2chatops by editing the `/opt/stackstorm/chatops/st2chatops.env
3. Test if the bot replies from Rocket.Chat: hubot help results in a list with commands
4. tail -f /var/log/syslog and try !st2 list actions
   The bot returns: Give me just a moment to find the actions for you... (details available at <url_omitted>)
   The log shows some action and task handling until:

Okay, I have found a fix (workaround) for the problem.

The problem is not StackStorm related but is upstream with the hubot-rocketchat adapter. Here RocketChat/hubot-rocketchat-boilerplate#4 (comment) is a fix specified.

A pull request (RocketChat/hubot-rocketchat#283 ) has been made but not merged.

@MrDiba An alternative to StackStorm's hubot is err-stackstorm which is based on errbot. You may find errbot supports rocketchat out-of-the-box.
