title: Unable to import module 'handler': Error for serverless
body: <p>Error: <code>Unable to import module 'handler': Error for serverless</code></p>
  
  <p>Here is my handler:</p>
  
  <pre><code>`use strict`
  const fetch = require('fetch')
  
  module.exports.hello = (event, context, callback) =&gt; {
    console.log('Hello, world!')
    callback(null)
  }
  </code></pre>
  
  <p>Here is my serverless.yml:</p>
  
  <pre><code>service: salsifyapicronjob
  provider:
    name: aws
    region: eu-central-1
    runtime: nodejs6.10
  functions:
    hello:
      handler: handler.hello
      events:
      - schedule:
          rate: cron(*/5 * * * ? *)
          enabled: true
  </code></pre>
  
  <p>I did notice inside the .serverless zip that the handler.js is not in there. Could this be the reason? And if so how do I fix that?</p>
