Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^12.2 -> satisfiable by phpunit/phpunit[12.2.0, ..., 12.5.7]. - phpunit/phpunit[12.2.0, ..., 12.5.7] require php >=8.3 -> your php version (8.2.30) does not satisfy that requirement.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires api-platform/parameter-validator ^3.4, found api-platform/parameter-validator[v3.4.0, ..., v3.4.17] but these were not loaded, likely because it conflicts with another require.
