I'm getting "TypeError: Cannot read property '_id' of undefined" when I attempt to use a Meteor Method on the client that inserts an object into a Mongo collection. I am using Collection2-core and Validated Method. The client side code that attempts to call the method is:

import { submitNewEvent } from '../../../api/events/events';

const newEvent = {
    eventName: "A String",
    eventDescription: "A String",
    eventPosition: {lat: 40, lng: -70},
};

submitNewEvent.validate(newEvent);
submitNewEvent.call(newEvent, (err, res) => {
    if (err) {
        console.log(err);
    } else {
        console.log(res);
    }
});

And the Method/Collection is defined within the module imports/api/events.js:

import { ValidatedMethod } from 'meteor/mdg:validated-method';

import eventSchema from './eventSchema';

Events = new Mongo.Collection('events');
Events.attachSchema(eventSchema);

export const submitNewEvent = new ValidatedMethod({
    name: 'submitNewEvent',
    validate: eventSchema.validator(),
    run({newEvent}) {
        Events.insert(newEvent);
    }
});

The eventSchema itself doesn't specify an _id field but all the other fields check out. Curiously, when I try to do a straight insert of the same object into the Collection from the server on startup, it works fine and there's no problem. What could be causing this issue from the method?

The entire error text is:

多亏了Buzz Moschetti的提示，才知道答案是什么！该方法在 newEvent 周围有尖括号，它本身已经是一个对象，因此文档在到达集合的过程中丢失了。
