wordpress wp_get_current_user data not displaying in jason-api

Question

I want to display a WordPress logged in user ID and email in another website so, I'm using the wordpressjson-api plugin to create an api but it's not working.
When I hit a direct link, it displays data as:

"{\"id\":1,\"email\":\"[email protected]\"}" 

But when I use json_decode and print data, it displays:

string(22) "{"id":0,"email":false}"

api code

public function get_loggedin_user_details() {
    global $user;
    global $wpdb, $json_api;
    $current_user = wp_get_current_user();
    $myObj->id = $current_user->ID;
    $myObj->email = $current_user->user_email;
    $logedin_userid = json_encode($myObj);
    return $logedin_userid;
  }

Here the process to get the logged in user id on WP:

1. install JWT Authentication for WP REST API plugin for rest-API authentication(read plugin description)

2. pass the login token you receive from the plugin to the route you created as Header: Authorization

3. create you custom Rest-API Route like this:

   add_action( 'rest_api_init', function () {
   register_rest_route( 'your_custom_route/v2', '/(?P<slug>[a-zA-Z0-9-]+)', array(
       'methods' => 'POST',
       'callback' => 'rest_api_custom_func',
       ) );
   } );
   
   function rest_api_custom_func(){ 
       global $user;
       global $wpdb;
       $current_user = wp_get_current_user();
       $myObj->id = $current_user->ID;
       $myObj->email = $current_user->user_email;
       $logedin_userid = json_encode($myObj);
       return $logedin_userid;     }
   

4. write your own function as a callback function on rest-api route :rest_api_custom_func

5. you can do whatever you want with your custom callback function

note: no need for any other plugin, use the built-in Wordpress Rest API
