Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires api-platform/laravel @dev -> satisfiable by api-platform/laravel[4.2.x-dev]. - api-platform/laravel 4.2.x-dev requires illuminate/config ^11.0 || ^12.0 -> found illuminate/config[v11.0.0, ..., 11.x-dev, v12.0.0, ..., 12.x-dev] but these were not loaded, likely because it conflicts with another require.
