WordPress REST API rest_comment_invalid_author Sorry, you are not allowed to edit ‘author’ for comments


I’m fairly new to WordPress REST API, but I have an Angular application which needs to take user’s input and then create a comment anonymously. To start off, we can get rid of the rest_comment_login_required error message by modifying the WordPress REST API function located in wp-includes/rest-api/endpoints/class-wp-rest-comments-controller.php file. The following line allows anonymous commenting:

$allow_anonymous = apply_filters( 'rest_allow_anonymous_comments', true, $request );

In my WordPress REST API, sending a GET request to http://localhost/wordpress/wp-json/wp/v2/users/1 returns:

    "id": 1,
    "name": "root",
    "url": "http://localhost/wordpress",
    "description": "",
    "link": "http://localhost/wordpress/author/root/",
    "slug": "root",
    "avatar_urls": {
        "24": "http://1.gravatar.com/avatar/d11662ae04f559ce691c5b1b4ff906f7?s=24&d=mm&r=g",
        "48": "http://1.gravatar.com/avatar/d11662ae04f559ce691c5b1b4ff906f7?s=48&d=mm&r=g",
        "96": "http://1.gravatar.com/avatar/d11662ae04f559ce691c5b1b4ff906f7?s=96&d=mm&r=g"
    "meta": [ ],
    "_links": {
        "self": [
                    "href": "http://localhost/wordpress/wp-json/wp/v2/users/1"
    "collection": [
            "href": "http://localhost/wordpress/wp-json/wp/v2/users"

So I only have one user currently in my database, who is called root.

If I simulate a request to the API with Postman and send a POST request to http://localhost/wordpress/wp-json/wp/v2/comments while supplying a raw JSON body thata looks like

    "content": "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
    "date": "2021-08-04T22:24:09",
    "post": 1,
    "author": 1,
    "author_name": "root",
    "author_url": "http://localhost/wordpress"

then I get an error

    "code": "rest_comment_invalid_author",
    "message": "Sorry, you are not allowed to edit 'author' for comments.",
    "data": {
        "status": 401

What is the meaning of this error and how do I fix this?
