Bug

What is the current behavior?

import { Model, Schema } from 'mongoose';

interface FooInterface {
    foo: string;
}

const fooSchema = new Schema<FooInterface, Model<FooInterface>, FooInterface>({ foo: { type: Schema.Types.String } });

interface BarInterface {
    bar: FooInterface[];
}

// Works
const barSchema = new Schema<BarInterface, Model<BarInterface>, BarInterface>({ bar: [fooSchema] });

// Does not work
const bar1Schema = new Schema<BarInterface, Model<BarInterface>, BarInterface>({
    bar: { type: [fooSchema], required: true },
});

What is the expected behavior?
Assigning a sub schema to type should work.
