I also have the same problem before. The code below works for me.

This is the code in the theme’s functions.php

// the external controller file
require 'json-api.php';

function add_hello_controller($controllers) {
  $controllers[] = 'iprofile';
  return $controllers;
}
add_filter('json_api_controllers', 'add_hello_controller');

function set_hello_controller_path() {
  return "../wp-content/themes/iProfile3/json-api.php";
}
add_filter('json_api_iprofile_controller_path', 'set_hello_controller_path');

For some reasons, I cannot use numbers in the controller names.
