It seems like $from defined by parameter $from on line 39 can also be of type object<Railt\Reflection\Contracts\Definition>; however, Railt\Reflection\Dictionary\CallbackDictionary::invoke() does only seem to accept null|object<Railt\Reflection\Contracts\Definition\TypeDefinition>, maybe add an additional type check?
