[InvalidArgumentException] Unknown connection scheme: 'redis'

[akutaktau]

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,
		]
	],

From the snippet you provided your url is redis: which isn't going to work. I've not used predis before. What are its connection strings supposed to look like?

[akutaktau]

This is my predis code.

<?php
include 'vendor/autoload.php';
require 'vendor/predis/Predis/autoload.php';

Predis\Autoloader::register();
$client = new Predis\Client('tcp://127.0.0.1:6379');
$client->set('foo', 'bar');
$value = $client->get('foo');
echo $value;
?>

I didn't set any password on redis. 127.0.0.1:6379 should be where my redis is running. Currently I'm just following https://book.cakephp.org/queue/1/en/index.html#configuration since the docs is stating using redis.

Try setting the following as your url key when configuring this library:

redis+predis://127.0.0.1:6379/0

[akutaktau]

Try setting the following as your url key when configuring this library:

redis+predis://127.0.0.1:6379/0

i still get the same error message.

'Queue' => [
		'default' => [
			  // A DSN for your configured backend. default: null
			  'url' => 'redis+predis://127.0.0.1:6379/0',
			  //'url' => 'redis://127.0.0.1:6379',

			  // 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,
		]

By the way I'm using the Queuing Mailer Actions. In case it help to be more specific.
