Description

Lint:container fails on prod with event name from parameter.

How to reproduce

# config/services.yaml
parameters:
    test_event: 'test_event'

services:
    App\EventListener\MyListener:
        tags:
            - { name: kernel.event_listener, event: '%test_event%' }

<?php

namespace App\EventListener;

use Symfony\Contracts\EventDispatcher\Event;

class MyListener
{
    public function onEvent(Event $test)
    {
        return $test;
    }
}

bin/console lint:container --env prod
[ERROR] Invalid definition for service "event_dispatcher": argument 1 of
"Symfony\Component\EventDispatcher\EventDispatcher::addListener" accepts "string", "array" passed.

Possible Solution

Not sure why it fails with this and why it only fails on prod and not on dev
