Unknown error when running command-line app.

Hi all,

I'm trying to run a command-line task, and my cli.php file is giving me this error:

PHP Notice:  Array to string conversion in /var/www/htdocs/classschedule/app/cli.php on line 23
PHP Fatal error:  Uncaught RuntimeException: Call to undefined method ::gettaskname() in /var/www/htdocs/classschedule/app/cli.php:23
Stack trace:
#0 /var/www/htdocs/classschedule/app/cli.php(23): Phalcon\Cli\Console->handle(Array)
#1 {main}
  thrown in /var/www/htdocs/classschedule/app/cli.php on line 23

Here is my cli.php

<?php
include '/var/www/common/dump.php';
require 'config/bootstrap.php';

$DI->get('dispatcher')->setDefaultNamespace('Task');
$DI->get('dispatcher')->setNamespaceName('Task');

$Console = new \Phalcon\CLI\Console();
$Console->setDI($DI);

$arguments = [];
foreach($argv as $k => $arg) {
    if($k == 1) {
        $arguments['task'] = $arg;
    } elseif($k == 2) {
         $arguments['action'] = $arg;
    } elseif($k >= 3) {
        $arguments['params'][] = $arg;
    }
}

try{
    $Console->handle($arguments); // <-- This is line 23
}
catch(\Phalcon\Exception $e){
    echo $e->getMessage();
    exit(255);
}

I have no idea why either the Notice or Fatal error are getting generated. This file is almost identical to the cli.php for another app I have, that runs just fine. Even taking out the foreach() still causes the error.
