setDefaultsOnInsert doesn't work if update is empty

[vkarpov15]

var assert = require('assert');
var mongoose = require('mongoose');

mongoose.connect('mongodb://localhost:27017/gh3617');

mongoose.set('debug', true);

var schema = new mongoose.Schema({
  test: { type: Number, default: 8472 },
  name: String
});

var MyModel = mongoose.model('MyModel', schema);

MyModel.update({}, { }, { setDefaultsOnInsert: true, upsert: true }, function(error) {
  assert.ifError(error);
  MyModel.findOne({}, function(error, doc) {
    assert.ifError(error);
    console.log(doc);
  });
});

How to write mongodb grammar? I still make the same mistake

[yinbucheng]

db.dataReference.update({ "dataId": "test" },
{ "$inc": { "referCnt": 1 },
"$set": { "updatedTimestamp": "1652257641341" },
"$setOnInsert": { "createdTimestamp": "1652257641341" ,"referCnt":100 }}
)

=============
WriteResult({
"nMatched" : 0,
"nUpserted" : 0,
"nModified" : 0,
"writeError" : {
"code" : 40,
"errmsg" : "Updating the path 'referCnt' would create a conflict at 'referCnt'"
}
})
4.4.6

@yinbucheng I'd recommend doing a separate update with $setOnInsert. So await db.dataReference.updateOne({ dataId: 'test' }, { $setOnInsert: { referCnt: 100 } }, { upsert: true }) followed by DataReference.update({}, { $inc: { referCnt: 1 } }) without the $setOnInsert or upsert.
