Phinx migration error, "Could not find class" but looking in the correct file?

I'm trying to run database migrations using the phinx library for a Phalcon framework example project called 'Vokuro' and I'm getting this error. The file directory is correct so I'm clueless as to why this is happening.

Cmd:

C:\xampp\htdocs\vokuro\vendor\bin>phinx.bat status -e development
Phinx by CakePHP - https://phinx.org.

using config file .\phinx.json
using config parser json
using migration paths
 - C:\xampp\htdocs\vokuro\db\migrations
using seed paths
 - C:\xampp\htdocs\vokuro\db\seeds
using environment development
ordering by creation time

In Manager.php line 742:

        $table = $this->table('email_confirmations');
        if ($table->exists()) {
            return;
        }

        $table->addColumn('usersId', 'integer')
            ->addColumn('code', 'char', ['limit' => 32])
            ->addColumn('createdAt', 'integer')
            ->addColumn('modifiedAt', 'integer', ['null' => true])
            ->addColumn('confirmed', 'char', ['limit' => 1, 'default' => 'N'])
            ->create();
    }
}

Because you are using your own config file:

using config file .\phinx.json

Instead of phinx.php. This file is located on the root of project. https://github.com/phalcon/vokuro/blob/master/phinx.php

Inside this file is paths key, which specifies namespaces for migrations and seeds.
