Issue

Followup ticket to #15298, #15312: ensuring we use async functions all the way through for improved stack traces. The goal is for the following script to show a full async stack trace with a pointer to the line of the original doc.save() call.

Error.stackTraceLimit = 20;

const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost:27017/mongoose_test");


const userSchema = new mongoose.Schema({
  name: { type: String, required: true, validate: v => v.length > 3 },
  age: Number,
});
userSchema.pre('validate', function() {
  if (this.name === 'secret') {
    throw new Error('name cannot be secret');
  }
});

const User = mongoose.model("User", userSchema);

async function runDemo() {
  const doc = new User({ name: 'A' });
  // await doc.validate().catch(err => console.log('Validate', err));
  await doc.save().catch(err => console.log('Save', err));
}

runDemo().catch(err => console.log(err.stack));

And ensure support for similar cases:

1. find()
2. findOne()
3. updateOne()
4. findOneAndUpdate()
5. insertMany()
6. bulkWrite()
7. Model.validate()
8. save() with user-defined pre hook that throws an error
9. save() with user-defined post hook that throws an error
