Mongoose - Update multiple fields in nested array

Question

I have below object.

{
  _id: ObjectId(6082adfaeced28382c167bd7),
  inviteMountaineers:
  [{
    _id: ObjectId(6082c4f9dcfaa86794601058),
    userId: ObjectId(60829eb5f1d2c316dfd79cd8),
    status:"Invited"
  },{
    _id: ObjectId(6082c4f9dcfaa86794601055),
    userId: ObjectId(60829eb5f1d2c316dfd79cd5),
    status:"Invited"
  }]
}

I want to update status of invited mountaineers and I tried using below code.

 const expedition = await Expedition.findOneAndUpdate(
  {
    _id: expeditionId,
    inviteMountaineers: {
      $elemMatch: { userId: mongoose.Types.ObjectId(userId) }
    }
  },
  { useFindAndModify: false },
  { $set: {
            'inviteMountaineers.$.status': status, 
            'inviteMountaineers.$.paidStatus': paidStatus,
            'inviteMountaineers.$.paidAmount': amount, 
          }
  }
).populate({
  path: 'inviteMountaineers',
  populate: {
    path: 'userId',
    model: 'User',
  },
})

This code returns the expedition object without any update. No update in the database also. Great if someone could help me with this.
