Mongoose doesn't save all the fields of my POST request - node.js

Question

I have a very simple "social network" app: users can register, write posts, like/unlike them and comment a post.
I have a probleme with my Post Schema :
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
// Create Schema
const PostSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: "user",
},
text: {
type: String,
required: true,
},
name: {
type: String,
},
avatar: {
type: String,
},
likes: [
{
user: {
type: Schema.Types.ObjectId,
ref: "user",
},
},
],
comments: [
{
user: {
type: Schema.Types.ObjectId,
ref: "user",
},
},
{
text: {
type: String,
required: true,
},
},
{
name: {
type: String,
},
},
{
avatar: {
type: String,
},
},
{
date: {
type: Date,
default: Date.now,
},
},
],
date: {
type: Date,
default: Date.now,
},
});
module.exports = Profile = mongoose.model("post", PostSchema);
When I receive my POST request for comments...
// #route POST api/posts/comment/:id
// #desc Add comment to post
// #access Private
router.post(
"/comment/:id",
passport.authenticate("jwt", { session: false }),
(req, res) => {
const { errors, isValid } = validatePostInput(req.body);
// Check Validation
if (!isValid) {
// If any errors, send 400 with errors object
return res.status(400).json(errors);
}
Post.findById(req.params.id)
.then(post => {
const newComment = {
text: req.body.text,
name: req.body.name,
avatar: req.body.avatar,
user: req.user.id,
};
console.log("newComment: ", newComment);
// Add to comments array
post.comments.unshift(newComment);
console.log("post: ", post.comments);
// Save
post.save().then(post => res.json(post));
})
.catch(err => res.status(404).json({ postnotfound: "No post found" }));
},
);
The only fields that are saved in the post.comments array is the User. Not the other fields (text, name, avatar, date).
My console.log("newComment: ", newComment); properly returns the complete object with all its properties but then, 2 lines below, console.log("post: ", post.comments); only returns the comment _id and the user and those are the only fields saved in the DB...
What did I miss here?

There is some Problem in the creation of the schema structure, this is the correct way:
comments: [
{
user: {
type: Schema.Types.ObjectId,
ref: "user",
},
text: {
type: String,
required: true,
},
name: {
type: String,
},
avatar: {
type: String,
},
date: {
type: Date,
default: Date.now,
},
}
]
the valid structure is nothing but like this(showing the changes made above):
comments: [{
user: {},
text: {},
// others...
}]
