title: mongodb collection.find not finding documents
body: <p>Absolute mongodb newbie here, and I must say I'm not impressed by the documentation. Anyway, my problem is I have a database on Mongodb Atlas, a Stitch application with a next.js frontend and trying to retrieve data like this:</p>
  
  <pre><code>import { setStitchClient } from '../utils/stitch';
  
  export default class MyPage extends React.Component {
    static async getInitialProps() {
      const stitchClient = await setStitchClient();
      const db = stitchClient.service('mongodb', 'mongodb-atlas').db('dbName');
  
      await stitchClient.login();
      const docs = await db
        .collection('test')
        .find()
        .limit(200)
        .execute();
      return { docs: docs };
  }
  
    render() {...}
  </code></pre>
  
  <p>The test collection includes 150 documents imported with mongoimport cli. I verified the documents are correctly imported. However the <code>.find()</code> above finds no records and the result is an empty array.
  If I create a document through the frontend in another collection, I can find it without problems. </p>
  
  <p>I guess there is no simple answer here but any hint would be highly appreciated. Thanks a lot!</p>
