Problems with $push

So, I’m trying to push a mongo ObjectId into an array. The model is the following:

const videos = new Schema({
    name: { type: String, required: true },
    likes: [{ type: ObjectId, ref: 'users', default: [] }],
    dislikes: [{ type: ObjectId, ref: 'users', default: [] }],
    views: { type: Number, default: 0 },
  }, {
    timestamps: true
  });

Then hooks are the following:

before: {
    patch: [
      authenticate('jwt'),
      isValidAction(),
      doLikeAction()
    ]
  }

the doLikeAction is the function not working

const doLikeAction = function(){
  return function(hook) {
    return new Promise((resolve, reject) => {
      hook.app.service('users').find({ query: { _id: hook.params.user._id }})
        .then(res => {
          hook.app.service('videos').update(hook.id, { $push: { likes: res.data[0]._id } })
          .then(res => {
            console.log(res)
            resolve(res)
          })
          .catch(err => {
            console.log(err)
            reject(new errors.BadRequest(constants.BAD_PARAMETERS));
          })
        })
    })
  }
}

It doesn’t say which error it is. The mongo ID are valid. The project is created using the yo generator. Hope you can help! Thank you 😃

Everything works fine with update, but it’s not what I meant to use. My bad. If instead of update I use patch (which is what I want to use), then it always fail.

.then(res => {
      return hook.app.service('videos').patch(hook.id, {
        $push: { likes: res.data[0]._id }
      });
    })

The point is that I’m not understanding why it fails and the error is not helping 😦 Moreover, I also would like to populate the likes field of the model. By adding:

const likesSchema = {
  include: {
    service: 'users',
    nameAs: 'like',
    parentField: 'likes',
    childField: '_id',
    query: {
      $select: ['_id', 'email']
    }
  }
};

and

after: {
    all: [],
    find: [],
    get: [],
    create: [],
    update: [],
    patch: [
      commonHooks.populate({ schema: likesSchema })
    ],
    remove: []
  }

it return a json with a like field in which there are the information relative to the current logged user (which _id is not in the likes array).

Thank for your reply hope you can help! 😃

@Fraccaman , Sorry my fault , the below code worked for patch

userDetails.patch(contextrecords.receiver_id, {
      $push: { approved_friends: contextrecords.sender_id }
    });
