Build events also want to handle.

Hi,

I've set up a Rocket.chat integration with your script, and added hook URL in my Gitlab CE.
When I'm not activating the script, gitlab send empty messages in Rocket.chat, and once activated nothing append.

I got GitLab 7.10.4 and Rocket Chat 0.34.0.

Do you have any idea to debug the script ?

Regards,

@sgrunt91 we use rocketchat version 0.35.0 and gitlab 8.9.3 for debugging you can try to add some console log in the script and look at the rocketchat log in the admin panel
