'Uncaught Error: Class "Symfony\Bundle\DebugBundle\DebugBundle" not found

I trying to deploy my application (Symfony 6 and php 8) through the Gandi.net french service. When I run the command to deploy the app by ssh I get the following error message in my terminal :

Script @auto-scripts was called via post-install-cmd

-----> Building new application failed

-----> Aborting deployment

This is the 2 files where the DebugBundle is mentioned.

  • Composer.lock

    "autoload": { "psr-4": {
    "Symfony\Bundle\DebugBundle\": ""
    },
    "exclude-from-classmap": [ "/Tests/"

    ]
    },

  • Bundles.php

    ['all' => true], Doctrine\Bundle\DoctrineBundle\DoctrineBundle::class => ['all' => true], Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle::class => ['all' => true], Symfony\Bundle\DebugBundle\DebugBundle::class => ['dev' => true], Symfony\Bundle\TwigBundle\TwigBundle::class => ['all' => true], Symfony\Bundle\WebProfilerBundle\WebProfilerBundle::class => ['dev' => true, 'test' => true], Symfony\WebpackEncoreBundle\WebpackEncoreBundle::class => ['all' => true], Twig\Extra\TwigExtraBundle\TwigExtraBundle::class => ['all' => true], Symfony\Bundle\SecurityBundle\SecurityBundle::class => ['all' => true], Symfony\Bundle\MonologBundle\MonologBundle::class => ['all' => true], Symfony\Bundle\MakerBundle\MakerBundle::class => ['dev' => true], Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle::class => ['all' => true], ];

The error suppose that I forgot a “use” but I never instantiate the DebugBundle so I never had to write a use for him. I try to run composer require symfony/debug-bundle and do a composer update but nothing change.
I already try to change de content of the composer.lock by changing :
"autoload": {
                "psr-4": {  
                    "Symfony\\Bundle\\DebugBundle\\": ""   
                }, 
                "exclude-from-classmap": [  
                    "/Tests/" 
                ]  
            },

To

"autoload": {  
                "psr-4": {  
                    "Symfony\\Bundle\\DebugBundle\\": “App\src”   
                },
                "exclude-from-classmap": [  
                    "/Tests/"   
                ] 
            },

but when the composer install or update is run the “App/src” is delete and the file return to is original value. I’m running out of idea so I hope your guys can help me.


Have a nice day.

I'm getting the same error, what I think is happening is that the composer command is installing the "prod" requirements, meaning it will correctly skip those bundles mentioned in "require-dev" as those are development only.

However, there must be some code in the runtime that isn't checking on which env it's running on or a misconfiguration that still tries to load all bundles when the Kernel is loading, (or it's not aware of the APP_ENV=prod), and therefor still tries to load the debug bundle (and other dev bundles), even though these were not installed by composer.

You'll notice these are the bundles that have dev => true in bundles.php. You'll notice that by removing these one by one, the error will shift to the next one that has dev => true.

I have made sure my env vars are set before any composer command is run, so it can't be that.

When SHH'ed into my server, I can go into the "bin" directory of my project and run "php console about" there. It seems to think it's a dev env, even though its deployment script ought to have set the APP_ENV var.

#php console about

Symfony

Long-Term Support No

Kernel

Type App\Kernel
Environment dev
Debug true
Charset UTF-8
Cache directory ./var/cache/dev (1.7 MiB)
Build directory ./var/cache/dev (1.7 MiB)
Log directory ./var/log (0 B)

PHP

Version 8.1.5
Architecture 64 bits
Intl locale en_US_POSIX
Timezone Europe/Brussels (2022-05-07T16:18:34+02:00)
OPcache true
APCu true
Xdebug false

So what I assume is that the "export APP_ENV=prod" and "export APP_DEBUG=0" are not remembered by the system.

Therefor, I ran "composer dump-env prod" manually on the system, and that generates a .env.local.php containing the APP_ENV and APP_DEBUG lines, and now these are respected and the site seems to load (onwards to fixing my data).
