The job was canceled because "_8_4" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - phpunit/phpunit[11.0.0, ..., 11.4.x-dev] require php >=8.2 -> your php version (7.4.6; overridden via config.platform, actual: 8.2.21) does not satisfy that requirement. - Root composer.json requires phpunit/phpunit ^11.0 -> satisfiable by phpunit/phpunit[11.0.0, ..., 11.4.x-dev].
