title: Google Cloud Function Finishes Execution But Never Enters Callbacks
body: <p>I am trying to make ~25 requests to fetch some data and save the response to separate files.
  I am using the npm request module to make the requests with a basic google cloud function.  Each request can take anywhere from 0.5 - 5 seconds to return a response.  When the script is setup to make less than 10 requests, everything works as expected and saves everything to the proper files.  However any more than that and I don't get a response from any request.    </p>
  
  <pre><code>for (i = 0; i &lt; popIDS.length; i++) {
      for (j = 0; j &lt; genreIDs.length; j++) {
          fetchAndSaveToFile(popIDS[i], genreIDs[j], date);            
      }
  }  
  </code></pre>
  
  <p><code>fetchAndSaveToFile</code> makes the npm request and uses pako to save the compressed response to a file in Google Cloud Storage.  This was originally an issue making ~5 requests but I increased the timeout for the function and it started working, however I maxed out the timeout for the function to 9 minutes.  All functions are currently in one file.</p>
  
  <p>Also it's worth noting that the value of popIDS[i], genreIDs[j] are not used inside the callback and 'i' and 'j' do not need to be captured.</p>
  
  <p>Do I need to make async requests differently for this to work?  I see there is async request module that handles this sort of thing. Are there function settings that I need to configure?  Or do I need to split this out into separate files so that I can set a 9 minute timeout for each request?    </p>
