Client(s) exhibiting the issue

I've been diving into different calendar applications to figure out what works best for me, i tried following the docker-compose.yml supplied to the best of my ability however, i believe these files are outdated and or missing details.

The image claims to be davis:latest however it should be ghcr.io/tchapi/davis-standalone:latest for the latest release as documented here.

After spending time finding the correct image and getting the mariadb and davis containers started i was able to connect to the port and was immediately greeted with a php exception error from Symfony

require_once('/var/www/davis/vendor/autoload_runtime.php') in[ /var/www/davis/public/index.php ](file:///var/www/davis/public/index.php#L14)(line 14)

    }
    use App\Kernel;
    use Symfony\Component\Dotenv\Dotenv;
    require_once dirname(__DIR__).'/vendor/autoload_runtime.php';
    if ($overridenEnvDir) {
        // Load our own now, after the runtime has booted
        (new Dotenv())->bootEnv($overridenEnvDir.'/.env');
    }

Stacktrace

Symfony\Component\ErrorHandler\Error\ClassNotFoundError:
Attempted to load class "WebProfilerBundle" from namespace "Symfony\Bundle\WebProfilerBundle".
Did you forget a "use" statement for another namespace?

Step 6) Start containers
Step 7) Make http request to port
Step 8) Greeted with PHP errors

Expected behaviour

no php exception errors

Actual behaviour

php exception errors

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following command:

'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

Additional context

No response

[tchapi]

The image claims to be davis:latest however it should be ghcr.io/tchapi/davis-standalone:latest for the latest release as documented here.

1. There are two flavours, you can see there are two Docker compose files in the Docker folder. Use the one that you see fit for your use case, there is a corresponding docker-compose file for each
2. the image tag in a docker-compose file where build is set is the name:tag applied to the built image. The comment is pretty explicit. True that edge has not been build for standalone, but you could just drop the tag, it would work (I've corrected the example compose file)

php exception errors

You didn't set APP_ENV=prod in your environment (step 1 of Installation)
