Bug.

What is the current behavior?
Nonexistent fields get omitted from query which yields unexpected results.

If the current behavior is a bug, please provide the steps to reproduce.

import mongoose from 'mongoose';
import assert from 'assert';

run().catch(console.error);

async function run () {
  mongoose.set('debug', true);
  await mongoose.connect('mongodb://localhost:27017/test');

  const userSchema = new mongoose.Schema({ name: String });
  const User = mongoose.model('User', userSchema);

  await User.create({ name: 'foo' });
  const user = await User.findOne({ wrongField: 'bar' });

  assert.strictEqual(user, null);
}

What is the expected behavior?
it shouldn't return any documents.

I can understand removing nonexistent fields from create or update, but imagine making a typo or having an old field which got removed from schema but not from the rest of our code in update filter. This could have significant unexpected results.

mongoose.set('strictQuery', false). We agree this change has had some unintended consequences and we're sorry for the inconvenience. Please use the workaround mongoose.set('strictQuery', false) for now if this causes you issues.

@vkarpov15 The option is not working for me (with Mongoose 6.2.9), no matter if I set it all the way at the beginning of my code, other after connecting mongoose.

@florianwalther-private make sure you do mongoose.set('strictQuery', false) before calling mongoose.model() or connection.model()

Sorry, I forgot to update this. My mistake was that I called it after setting up my routes (which in turn had dependencies on the models). It's all working now, I just needed to call it early enough :)
