Can't get it to work with code

Trying to get this to work with a custom module but I'm getting the same error as Fatal error when deleting Heartbeat Template.

I'm using the statuses module for my first test but I plan to use heartbeat for a lot of activity. This is just test 1 but I can't get it to work. The statuses module is not currently working with rules so I can't make a rule for when a status is submitted. Either way I'd really prefer to do this with a custom module.

I have a function that is executed when a status is submitted, there I have this code:

global $user;
$message_id = 'user_updated_status';
$variables = array(
  '@username' => l(custom_full_name($user->uid), 'user/' . $user->uid),
  '@node_type' => 'status',
  '@node_title' => l('status', 'statuses/' . $status->sid),
);
heartbeat_api_log($message_id, $user->uid, 0, $status->sid, 0, $variables);

And then I have a custom module with this code:

function my_module_heartbeat_message_info() { 
  $info = array( 

    0 => 
    array( 
      'message' => '!username updated his/her !node_title', 
      'message_concat' => '!user updated his/her !node_title', 
      'message_id' => 'user_updated_status', 
      'concat_args' => 
		  array( 
			'type' => '', 
			'group_by' => '', 
			'group_target' => '', 
			'group_by_target' => '', 
			'group_num_max' => '', 
			'merge_separator' => ',', 
			'merge_end_separator' => '', 
			'roles' => 
				array( 
				  0 => '0', 
				  1 => '0', 
				  2 => '0', 
				  3 => '0', 
				  4 => '0', 
				  5 => '0', 
			), 
		  ), 
      'description' => 'User updated status', 
      'perms' => '1', 
      'custom' => '0', 
      'variables' => 
      array( 
      ), 
    ), 
  ); 

  return $info; 

}

When I try to post a status which of course was working fine before I get:

An AJAX HTTP error occurred.
HTTP Result Code: 500
Debugging information follows.
Path: /statuses/ajax
StatusText: error
ResponseText: Recoverable fatal error: Argument 2 passed to HeartbeatActivity::__construct() must be an instance of HeartbeatMessageTemplate, null given, called in /www/sites/all/modules/heartbeat/heartbeat.module on line 612 and defined in HeartbeatActivity->__construct() (line 67 of /www/sites/all/modules/heartbeat/includes/heartbeatactivity.inc).

So I guess this means I don't have a template but again I can't use rules and I thought the hook_heartbeat_message_info() was to create the template.

Any help?
