[InvalidArgumentException] Unknown connection scheme: 'redis'

I've been trying this plugin for mailing purpose. Somehow I've an issue connecting to redis.

When I'm using predis directly, I can't connect and submit my data to the redis.

This is my stack trace

My configuration look like this.

'DebugKit' => [
        'ignoreAuthorization' => true,
    ],
	
	'Queue' => [
		'default' => [
			  // A DSN for your configured backend. default: null
			  'url' => 'redis:',
			  //'url' => 'redis://127.0.0.1:6397',

			  // The queue that will be used for sending messages. default: default
			  // This can be overriden when queuing or processing messages
			  'queue' => 'default',

			  // The name of a configured logger, default: null
			  'logger' => 'stdout',

			  // The name of an event listener class to associate with the worker
			  //'listener' => \App\Listener\WorkerListener::class,
		]
	],

Commencez par la configuration de Queue présentée dans l’issue et suivez la connexion Redis à travers les entrées mentionnées RedisConnectionFactory.php et PRedis.php. Reproduisez l’erreur de schéma inconnu signalée, puis vérifiez que la DSN Redis configurée est acceptée et que queued mail peut se connecter sans cette exception.
