Model.bulkWrite weird behaviour

[wisdomabioye]

Prerequisites

• I have written a descriptive issue title

Mongoose version

7.3.0

Node.js version

18.15.0

MongoDB version

6.0.6

Operating system

Linux

Operating system version (i.e. 20.04, 11.3, 10)

Issue

Consider this code snippet

async function performBulkWrite(operations) {
  // ...
  console.log('before write');
  await Model.bulkWrite(operations);
  console.log('after write'); // this line never logged if operations.length === 0
  // ...
}

This code never reach here console.log('after write'); if operations.length === 0;

Is this the right behaviour?

I have fixed it using if (operations.length === 0) { ... } but I'm still curious.

const mongoose = require('mongoose');

const testSchema = new mongoose.Schema({ 
  name: String
});

const Test = mongoose.model('Test', testSchema);

async function run() {
  await mongoose.connect('mongodb://localhost:27017');
  await mongoose.connection.dropDatabase();

  const array = [];

  await Test.bulkWrite(array);
  console.log('done');
}

run();
