Reproducing mongoose post init error handling

gistfile1.txt

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var uri = 'mongodb://localhost:27017/development';

mongoose.connect(uri, function (err) {
    if (err) throw new Error(err);
    console.log(`Connected to ${uri}`);

    var TestSchema = new Schema();

    TestSchema.post('init', function (model, next) {
        return next(new Error(`Failure ${model._id}`));
    });

    var TestModel = mongoose.model('Test', TestSchema);

    var modelsToSave = [];

    for (var i = 0; i < 10; i++) {
        modelsToSave.push(new TestModel());
    }

    Promise.all(modelsToSave.map(model => model.save()))
        .then(() => {
            var i = 0;
            TestModel.find({},
                // called multiple times
                function (err) {
                    console.log(`called ${++i} times`, err);
                });
        });
});
