Add a Ray by Spatie helper to catch WP Errors

ray-wp-error-helper.php

<?php
/*
 * Create a file at wp-content/mu-plugins/ray-wp-error-helper.php and add this entire gist
 * https://myray.app/
 */
add_action('wp_error_added', function ($code, $message, $data, $wp_error) {
    ray($wp_error);
    ray()->trace();
}, 10, 4);

Should see something like this:

To generate the above, I had this in my code, but that filter will pick up on all internal WP errors as well as any custom errors.

new \WP_Error('example_error', __('Something really bad is happening.'), ['user' => get_current_user()]);
