Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires datana-gmbh/iusta-api ^1.4 -> satisfiable by datana-gmbh/iusta-api[1.4.0]. - datana-gmbh/iusta-api 1.4.0 requires php >=8.1 -> your php version (7.4.33) does not satisfy that requirement.
