REST put request to update geojson document in MongoDB using Node.js and Mongoose

I've been following a Youtube tutorial on creating a RESTful API (I'm just getting to grips with this field). The tutorial is about books, but I wanted to extend it to support geoJSON as that's my end goal.

I have no problem updating fields if they're at the root of the document such as: 

first_name: object.first_name,

What I don't understand is how to update fields that exist as part of a subdocument: 

geometry: { coordinates: [] },

I've tried using geometry.coordinates and the above structure, nether of which have worked.

Here's what I have:

Update Function from object model

// Update Object
module.exports.updateObject = function(id, object, options, callback)
{
    var query = { _id: id};
    var update = {
            geometry:
            {
                type: object.geometry.type,
                coordinates: object.geometry.coordinates
            },
            properties:
            {
                icon: object.properties.icon,
                title: object.properties.title,
                description: object.properties.description
            }

    }
    User.findOneAndUpdate(query, update, options, callback);
};

app put function from app.js

app.put('/api/objects/:_id', function(req, res)
{
    var id = req.params._id
    var object = req.body;

    Object.updateObject(id, object, {}, function(err, object)
    {
        if (err)
        {
            res.json(err);
        } 

        res.json(object);
    });
});

PUT Request from web

{
    "geometry": 
    {
        "type": "Point",
        "coordinates": [-90.5299938027191,                  24.42859997065679]
    },
    "properties":
    {
        "icon": "bar-15",
        "title": "Bar",
        "description": "A Bar"
     }    
}

  },

Found the issue:

I C+P'd the code from another part of my code and failed to noice that I hadn't updated the following line:

User.findOneAndUpdate(query, update, options, callback);

to:

Object.findOneAndUpdate(query, update, options, callback);

You can use $set to update non root fields

User.findOneAndUpdate({
  _id: id
}, {
  $set: {
    geometry: {
      type: object.geometry.type,
      coordinates: object.geometry.coordinates
    },
    properties: {
      icon: object.properties.icon,
      title: object.properties.title,
      description: object.properties.description
    }
  }
}, {
  new: true
}, (err, doc) => {
  console.log('err', err);
  console.log('doc', doc);
});
