title: Error deploying Firebase Cloud Functions on Node runtime 10, but works on Node runtime 8
body: <p>I am trying to implement geofirestore in my cloud functions.</p>
  
  <p>The functions deploy correctly in Node runtime 8, but there is an error in deployment in runtime 10.</p>
  
  <p>My index.js header is as below:</p>
  
  <pre><code>const functions = require("firebase-functions");
  const admin = require("firebase-admin");
  const { GeoCollectionReference, GeoFirestore, GeoQuery, GeoQuerySnapshot } = require('geofirestore');
  admin.initializeApp();
  
  const db = admin.firestore();
  const geofirestore = new GeoFirestore(db);
  </code></pre>
  
  <p>The error message I get on Node runtime 10 is:</p>
  
  <pre><code>i  deploying functions
