title: How to remove property of nested object from MongoDB document?
body: <p>I have a MongoDB document like this : </p>
  
  <pre><code>{
      "_id": ObjectId("5589044a7019e802d3e9dbc5"),
      "sessionId": LUUID("f49d4280-ced0-9246-a3c9-a63e68e1ed45"),
      "teamId": LUUID("6ef7d1a8-f842-a54c-bd8c-daf6481f9cfc"),
      "variableId": LUUID("59d1b512-eee2-6c4b-a5b5-dda546872f55"),
      "values": {
          "725400": 691.0000000000000000,
          "725760": 686.0000000000000000,
          "726120": 683.0000000000000000,
          "726480": 681.0000000000000000,
          "726840": 679.0000000000000000,
          "727200": 678.0000000000000000,
          "727560": 677.0000000000000000,
          "727920": 676.0000000000000000
      },
      "variableType": 2,
      "isSet": false,
      "teamNumber": 2,
      "simPageIds": []
  }
  </code></pre>
  
  <p>I have a scenario that I have to delete a particular property from the <code>"values"</code> property of my document. for example, I want to delete value <code>"727920"</code> from the <code>"values"</code> property. </p>
  
  <p>Since <code>"Values"</code> is not an array, I can't use <code>$pull</code> here. What I need is to remove </p>
  
  <p><code>"727920" : 676.0000000000000000</code> from <code>"values"</code>. </p>
  
  <p>What is the right way to do that?   </p>
