spacebro GUI crashes when receiving big objects

[negabakuru]

I use spacebro with my app to broadcast infos about requests made to the twitter API.
After my app posts a tweet, I want to send twitter's response through spacebro.
The object I send to spacebro looks like this:

{ action: 'twitter',
  success: true,
  code: 200,
  response: 
   { created_at: 'Thu Jul 13 13:48:56 +0000 2017',

     favorite_count: 0,

When spacebro receive the event it crashes with this message:
