title: MongoError: filter parameter must be an object
body: <p>I am creating a rest api I have end point for Post/Movies: Request body should contain only movie title, and its presence should be validated Based on passed title, other movie details should be fetched from thememoviedb,and saved to application database.</p>
  
  <pre><code>app.post('/movies', (req, res) =&gt; {
          request('https://api.themoviedb.org/3/discover/movie?callback=JSONP_CALLBACK&amp;sort_by=popularity.desc&amp;api_key=2931998c3a80d7806199320f76d65298', function (error, response, body) {
              console.log('error:', error); // Print the error if one occurred and handle it
              console.log('statusCode:', response &amp;&amp; response.statusCode); // Print the response status code if a response was received
  
            });
          db.collection('movies').findOneAndUpdate(req.body.title,{
              title: 'Avengers',
          },(err, result) =&gt; {
              if (err) {
                  res.send({
                      'error': 'An error has occured'
                  });
              } else {
                  res.send(result.ops[0]);
              }
          });
  });
