title: GoogleSpreadsheet is not a constructor error
body: <pre class="lang-js prettyprint-override"><code>(node:13696) UnhandledPromiseRejectionWarning: TypeError: GoogleSpreadsheet is not a constructor
  </code></pre>
  
  <p>Currently getting this error when trying to define GoogleSpreadsheet. Not sure what the issue could be here.</p>
  
  <pre class="lang-js prettyprint-override"><code>async function accessSpreadsheet() {
      const doc = new GoogleSpreadsheet('166SrAlBzhYXLxxIrHCQR333y_w3pcxeG7rV3bkjAp2U');
      await promisify(doc.useServiceAccountAuth)(creds);
      const info = await promisify(dox.getInfo)();
      const sheet = info.worksheets[0];
  
      const input = {
          transcript: data,
          ticket: message.channel.name
      }
  
      await promisify(sheet.addRow);
  }
  
  accessSpreadsheet();
  </code></pre>
  
  <p>Above is my code, not all of it, but everything to do with google spreadsheet.</p>
