Cannot read property 'browserify' of undefined

[dionysio]

I have installed your plugin, enabled it in my serverless.yml. I have not used any custom configuration and this happens on deployment:

Serverless: SlsBrowserify::validate
Serverless: SlsBrowserify::globalConfig

  Type Error ---------------------------------------------

     Cannot read property 'browserify' of undefined

     For debugging logs, run again after setting SLS_DEBUG env var.

  Stack Trace --------------------------------------------

I'm having the same problem, using it on the unmodified aws-node-rest-api-with-dynamodb example.

 Node Version:       6.9.1
 Serverless Version: 1.5.0

[predescu]

a workaround is to add into serverless.yml

custom:
  browserify:

probably the solution is to change lib/configure.js on line 15 to check if this.serverless.service.custom is defined or not
