How to use doctrine in SlimPHP with DB2? - doctrine-orm

Question

I am trying use Doctrine within Slim to connect to a DB2 db. I am getting no errors. But, my app is not connecting to the database. I am using (likely incorrectly) this package for the driver: alanseiden/doctrine-dbal-ibmi
Here is the pertinent bit from my DIC:
// Doctrine
$container['db'] = function ($c) {
$settings = $c->get('settings');
$config = \Doctrine\ORM\Tools\Setup::createAnnotationMetadataConfiguration(
$settings['doctrine']['meta']['entity_path'],
$settings['doctrine']['meta']['auto_generate_proxies'],
$settings['doctrine']['meta']['proxy_dir'],
$settings['doctrine']['meta']['cache'],
false
);
return \Doctrine\ORM\EntityManager::create($settings['doctrine']['connection'], $config);
};
And, the referenced settings:
// doctrine settings
'doctrine' => [
'meta' => [
'entity_path' => [
'app/src/Entity'
],
'auto_generate_proxies' => true,
'proxy_dir' => __DIR__.'/../cache/proxies',
'cache' => null,
],
'connection' => [
'Description' => 'IBM i Access ODBC Driver 64-bit',
'driver' => '\DoctrineDbalIbmi\Driver\DB2Driver::class',
'System' => 'xx.xx.xx.xx',
'UserID' => '*****',
'Password' => '*****',
'Naming' => 0,
'DefaultLibraries' => 'QGPL',
'ConnectionType' => 0,
'CommitMode' => 2,
'ExtendedDynamic' => 1,
'DefaultPkgLibrary' => 'QGPL',
'DefaultPackage' => 'A/DEFAULT(IBM),2,0,1,0,512',
'AllowDataCompression' => 1,
'MaxFieldLength' => 32,
'BlockFetch' => 1,
'BlockSizeKB' => 128,
'ExtendedColInfo' => 0,
'LibraryView' => 'ENU',
'AllowUnsupportedChar' => 0,
'ForceTranslation' => 0,
'Trace' => 0
]
]
],
];
I appreciate any help or direction.
