Type of VladimirYuldashev\LaravelQueueRabbitMQ\Queue\RabbitMQQueue::$config must not be defined (as in class Illuminate\Queue\Queue)

[SuperIbm]

• Laravel/Lumen version: 12.34.0
• RabbitMQ version: 3.13.4
• Package version: 14.3.0

Describe the bug

I have error when I dispatch any jobs:

Type of VladimirYuldashev\LaravelQueueRabbitMQ\Queue\RabbitMQQueue::$config must not be defined (as in class Illuminate\Queue\Queue)

After Laravel 12.33.0 they added protected $config; in Illuminate\Queue\Queue that doesn't have the type parameter.

Applying the RabbitMQ Laravel 12.35 Compatibility Patch

Issue

Laravel 12.34+ introduced a $config property in the base Illuminate\Queue\Queue class without type hints. The RabbitMQ package defines the same property with a QueueConfig type hint, causing a PHP fatal error due to property variance rules.

Solution

This patch uses Composer Patches to rename the conflicting property and adjust method visibility to match the parent class.

Installation Steps

1. Install the composer-patches plugin:

composer require cweagans/composer-patches

2. Add patch configuration to composer.json:

{
  "extra": {
    "patches": {
      "vladimir-yuldashev/laravel-queue-rabbitmq": [
        "patches/rabbitmq-laravel-12-compat.patch"
      ]
    }
  }
}

3. Place the provided patch file in patches/rabbitmq-laravel-12-compat.patch
4. Reinstall the package to apply the patch:

rm -rf vendor/vladimir-yuldashev/laravel-queue-rabbitmq

composer install

5. Verify the patch was applied:
   You should see this output during installation:

- Applying patches for vladimir-yuldashev/laravel-queue-rabbitmq
    patches/rabbitmq-laravel-12-compat.patch (0)

Removing the Patch

Once the official fix is released (see #638):

1. Update the package:

composer update vladimir-yuldashev/laravel-queue-rabbitmq

2. Remove the patch section from composer.json
3. Delete the patch file:

rm patches/rabbitmq-laravel-12-compat.patch
