Cannot dispatch job inside subscribe closure about laravel-client

[Namoshek]

Using the sync queue driver is a bad idea in this case as it will run the job during execution of the MQTT client which can cause a lot of different issues, especially timeouts.

The redis driver however should work and I'm not sure why it doesn''t. I've not been using the MQTT client with Laravel for quite some time, so I don't have a suitable test setup right now. Maybe you can 1) provide the full code (Artisan command and job) as well as 2) try to dispatch the job differently: Bus::dispatch(new HandleMqttMessage($topic, $message)). If I'm not wrong, dispatching the way you did will only dispatch the job on disposal and that might be an issue here.

By the way, how many messages are you processing at this time?
