I recently added the following code to the functions.php part of my theme form editor to make a hook that makes a new message within my made CPT (members) when someone signs up using the ‘Tutor Registration’ form:

function create_cpt_on_user_registration( $user_id ) {
    // Get user data
    $user_info = get_userdata( $user_id );
    // Get the first and last name
    $first_name = $user_info->first_name;
    $last_name = $user_info->last_name;
    // Construct the post title with first and last name
    // Original: $post_title="New User Post: " . $first_name . ' ' . $last_name;
    $post_title = $first_name . ' ' . $last_name; // Edited to just first and last name
    // Construct the post content with first and last name
    $post_content="This post was created automatically for user: " . $first_name . ' ' . $last_name;
    // Define the post details for your CPT
    $post_data = array(
        'post_title'    => $post_title,
        'post_content'  => $post_content,
        'post_status'   => 'publish', // Or 'draft', 'pending' etc.
        'post_type'     => 'members', // The slug of your custom post type
        'post_author'   => $user_id  // Set the author of the new post to the new user
    );
    // Insert the post
    wp_insert_post( $post_data );
}
add_action( 'user_register', 'create_cpt_on_user_registration' );

I then added the code to a code filler to try to solve the problem, and it gave me the following code:

function create_cpt_on_user_registration( $user_id ) {
    // Get user data
    $user_info = get_userdata( $user_id );
    // Get the first and last name
    $first_name = $user_info->first_name;
    $last_name = $user_info->last_name;
    // Construct the post title with first and last name
    $post_title = $first_name . ' ' . $last_name;
    // Construct the post content with first and last name
    $post_content="This post was created automatically for user: " . $first_name . ' ' . $last_name;
    // Define the post details for your CPT
    $post_data = array(
        'post_title'    => $post_title,
        'post_content'  => $post_content,
        'post_status'   => 'publish', // Or 'draft', 'pending' etc.
        'post_type'     => 'members', // The slug of your custom post type
        'post_author'   => user_can( $user_id, 'publish_posts' ) ? (int) $user_id : 1
    );
    // Insert the post
    wp_insert_post( $post_data );
}
add_action( 'user_register', 'create_cpt_on_user_registration' );

This did not solve the problem either.

I can see that only 2 arguments are adopted when I believe it expects 12 (from the stacking trace). How can I solve this problem?
