No configured handlers in Symfony Messenger - php

Question

I'd like to implement Messenger async handlers and be able to queue some tasks in Redis, but I can't for some reason.
Here is my global config :
PHP 7.3.16
Symfony 4.4.7
Messenger 4.4
Redis 5.0.3
Predis 1.1
I tried to follow this guide :
https://symfony.com/doc/4.4/messenger.html
Everything is a copy/paste from the doc, except that I replaced my controller with a command.
This dispatch command seems to work :
php bin/console app:dispatch-command
^ Symfony\Component\Messenger\Envelope^ {#5465 -stamps: []
-message: App\Message\SmsNotification^ {#5475
-content: "Look! I created a message!" } }
This command returns no configured handlers :
php bin/console debug:messenger
Messenger
=========
This second command returns an error while trying to consume a message
php bin/console messenger:consume async
TypeError {#174
#message: "The first argument must be an instance of "Symfony\Component\Messenger\RoutableMessageBus"."
#code: 0

Can someone please help me?
Cheers!
Update
I tried to manually route my handlers as explained in the doc :
# config/services.yaml
App\MessageHandler\SmsNotificationHandler:
tags: [messenger.message_handler]
But it changes nothing.
I also checked if my message and message Handler were registered as services, and it is :
php bin/console debug:container App
[70 ] App\Message\SmsNotification
[71 ] App\MessageHandler\SmsNotificationHandler

Answer 1

I still don't know what causes this issue, but I just succeeded to resolve it by installing a whole new Symfony 4.4.7 project and by overwriting it.
I also figured out that swiftmailer was replaced by mailer, and twig-bundle by twig-pack, but only for new projects, without beeing notice by composer for existing installations (even using composer update/upgrade/recipes. It may be the cause of my problems but I'm not sure.
Step 1 : create a new Symfony 4.4.7 project
composer create-project symfony/website-skeleton newProj ^4.4.7
sudo chown -R $USER:www-data
cd /newProj
Step 2 : overwrite with my git project
git init
git remote add origin $url_of_clone_source
git fetch origin
git checkout -b master --track origin/master
Step 3 : install vendors and replace obsolete dependencies
composer install
composer remove symfony/swiftmailer
composer require symfony/mailer
composer remove symfony/twig-bundle
composer require symfony/twig-pack
Step 4 : check messenger
$ php bin/console debug:messenger
Messenger
=========
messenger.bus.default
---------------------
The following messages can be dispatched:
----------------------------------------------------------
App\Message\SmsNotification
handled by App\MessageHandler\SmsNotificationHandler
Symfony\Component\Mailer\Messenger\SendEmailMessage
handled by mailer.messenger.message_handler
----------------------------------------------------------
