You are missing a "cli-config.php" or "config/cli-config.php" file in your
project, which is required to get the Doctrine-DBAL Console working. You can use the
following sample as a template:

<?php
use Doctrine\DBAL\Tools\Console\ConsoleRunner;

// replace with the mechanism to retrieve DBAL connection in your app
$connection = getDBALConnection();

// You can append new commands to $commands array, if needed

return ConsoleRunner::createHelperSet($connection);

HELP;
    }
