Crash on SLS 2.23.0

Hi,

Been using this plugin for a long time now, but it appears 2.22+ crashes on bootstrap.

Serverless: Loading cloudside resources for 'api-staging' stack.
 
  Type Error ---------------------------------------------

It can't find error, but it can find catch (https://github.com/jeremydaly/serverless-cloudside-plugin/blob/33708ff196921f8b2f1c79a350c500c329327d0c/index.js#L230)

I made the change, and it works fine now. Just a heads up for anyone else running into this.
