Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires spatie/typescript-transformer v3.x-dev#40e9b98 -> satisfiable by spatie/typescript-transformer[v3.x-dev]. - spatie/typescript-transformer v3.x-dev requires php ^8.2 -> your php version (8.1.21) does not satisfy that requirement.
