Top-level use of w, wtimeout, j, and fsync is deprecated. Use writeConcern instead.

I am getting this error when

await TaskModel.updateOne(
  {
    name
  },
  {
    state: 'requested'
  },
  {
    upsert: true,
    writeConcern: {
      w: 'majority',
      j: true,
      wtimeout: 15000
    }
  }
).exec()

It does not seem like a top-level w, j, etc. and I am using writeConcern. What am I doing wrong?

Mongoose version: 5.11.18.

@ChoppinBlockParty I see the same thing on my end; it looks like maybe there are some defaults injected?

If you change the writeConcern object to a string, like so <<writeConcern: 'majority'>>, you no longer get the warning. I am guessing the object approach has a bug.

@dbronin Sorry, did not get it. How do i need covert the writeConcern?

[dbronin]

@ChoppinBlockParty I am not sure that you can if you need all 3 parameters. If you want to just specify the w, you can set writeConcern: 'majority'

it looks like this is related to a change on MongoClient

const mongoose = require('mongoose');

const UserSchema = mongoose.Schema({
  email: { type: String, required: true },
  firstName: { type: String, required: true },
  lastName: { type: String, required: true }
},{autocreate:true});

const User = mongoose.model('User', UserSchema);

(async function() {
  await mongoose.connect('mongodb://localhost:27017/test', {
    useNewUrlParser: true,
    useUnifiedTopology: true
  });

  const user = await User.create({
    email: 'bill@microsoft.com',
    firstName: 'Bill',
    lastName: 'Gates'
  });

  User.updateOne({firstName: 'Bill'},{firstName: 'Jill'},{upsert:true, writeConcern: {w:'majority', j:true, wtimeout:15000}}).exec();
  console.log('Done', user.firstName);
})();

I set up the write concern like this

const MySchema = new Schema(
    {
        _id: { type: Number, required: true },
        requestId: { type: Types.ObjectId, required: true },
        op: { type: String, required: true },
        size: { type: Number, required: true },
        totalSize: { type: Number, required: true }
    },
    {
        versionKey: false,
        writeConcern: {
            w: 'majority',
            j: true,
            wtimeout: 15000
        }
    }
)

I still continue to get the warning even with 5.12.3 (mongodb@3.6.5) version.
