syntax errors in handler obscured - reports as iopipe-handler error

[ewindisch]

if my own handler has a syntax error I get:

Syntax error in module 'iopipe-handlers': SyntaxError
SyntaxError: Unexpected token )
at createScript (vm.js:56:10)
at Object.runInThisContext (vm.js:97:10)
at Module._compile (module.js:542:28)

at Module.require (module.js:497:17)
at require (internal/module.js:20:19)
at Object.<anonymous> (/var/task/iopipe-handlers.js:3:27)

The error in my own code is not logged.
