When I try to execute this app:

#!/usr/bin/perl

use Dancer;
use Dancer::Plugin::SimpleCRUD;

# Simple example:
simple_crud(
    record_title => 'Player',
    prefix => '/player',
    db_table => 'jugador',
    editable => 1,
);

dance;

I get as my result in the browser:

Error 404

Unable to process your query

-- This is my config.yml file:

plugins:
    Database:
        driver: 'mysql'
        database: 'my_main_DB'

Any help is greatly appreciated. Thank you
