Answer 1

Try to do the import like this way const {CharacterSchema} = require(__dirname +'/CharacterModel.js').schema;

Adding the .schema at the end.

UserSchema :

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

const CharacterSchema = new Schema({
    name: {
        type: String,
        required: true
    },
    title: {
        type: String
    },
    charcterClass: { 
        type: String
    },
    level: {
        type: Number
    }
});

const UserSchema = new Schema({
    name: {
        type: String, 
        required: true
    } ,
    characters:{ 
        type:[CharacterSchema]
    }
});

const User = mongoose.model('User', UserSchema);
module.exports = User;
