Mongoose findById query does not return a result. Object is always null.

findById doesn't return a result. const course object is null everytime I log.

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/mongo-exercises', { useNewUrlParser: true });

const courseSchema = new mongoose.Schema({
    name: String,
    author: String,
    tags: [ String ],
    date: Date,
    price: Number,
    isPublished: Boolean
});

const Course = mongoose.model('Course', courseSchema);

async function updateCourse(id){
        const course = await Course.findById(id);
        if(!course) return;

        course.isPublished = true;
        course.author = 'Another Author';

        const result = await course.save();
        console.log(result);
}

updateCourse('5a68fde3f09ad7646ddec17e');

The issue has been resolved. I noticed that when I imported the collection prior to updating by .findById(); the id's of the objects were saved as Strings instead of ObjectID
