title: Mongoose: BSON field returns empty on model schema
body: <p>I have the folowing documents on MongoDB:</p>
  <pre><code>{
      &quot;_id&quot;: {
          &quot;$oid&quot;: &quot;5fddb4f404df1a32044f1f82&quot;
      },
      &quot;name&quot;: &quot;1pc Chicken McDo with Spaghetti Meal&quot;,
      &quot;description&quot;: &quot;1pc Chicken McDo with Spaghetti Meal&quot;,
      &quot; price &quot;: 144,
      &quot;image&quot;: &quot;1pc-chicken-mcdo-with-spaghetti-meal.png&quot;,
      &quot;locations&quot;: {
          &quot;$regex&quot;: &quot;[\&quot;Angeles, Pampanga\&quot;, \&quot;Baguio City\&quot;, \&quot;Cabanatuan, Nueva Ecija\&quot;, \&quot;Mabalacat, Pampanga\&quot;, \&quot;Makati\&quot;, \&quot;Mandaluyong\&quot;, Pasay\&quot;, Pasig\&quot;, San Fernando, Pampanga\&quot;, San Jose, Nueva Ecija\&quot;, San Juan\&quot;, Taguig\&quot;]&quot;,
          &quot;$options&quot;: &quot;&quot;
      }
  }
  </code></pre>
  <p>Following that structure, I made this schema code on NodeJS. Notice that the last field which is <code>location</code> is declared as an array of flat String type.</p>
  <pre><code>var productSchema = new Schema({
    name: String,
    description: String,
    price: Decimal128,
    image: String,
    location: [{type: String}]
  });
  </code></pre>
  <p>My problem is that everything else works when I try to retrieve the data using <code>find()</code> except for that <code>location</code> field. Here is an example of what the y model returns:</p>
  <pre><code>[
    {
      &quot;location&quot;: [
        
      ],
      &quot;_id&quot;: &quot;5fddb4f404df1a32044f1f82&quot;,
      &quot;name&quot;: &quot;1pc Chicken McDo with Spaghetti Meal&quot;,
      &quot;description&quot;: &quot;1pc Chicken McDo with Spaghetti Meal&quot;,
      &quot; price &quot;: 144,
      &quot;image&quot;: &quot;1pc-chicken-mcdo-with-spaghetti-meal.png&quot;,
      &quot;locations&quot;: {
        
      }
    },
  ]
  </code></pre>
  <p>As you can see, the location field remains empty despite everything else returning fine.</p>
  <p>Can somebody help me figure this one out?</p>
  <p>Thanks.</p>
