Start with the provided docker-compose.yml and reproduce the 500 error, then trace the failure from src/ServiceProvider/MongoStorageProvider.php into vendor/alcaeus/mongo-php-adapter/lib/Alcaeus/MongoDbAdapter/Helper/ReadPreference.php at line 41. Check the MongoDB driver compatibility involved; done means the Docker setup starts successfully and the application loads without the undefined-constant error.
