Consider using $parameterReflection->name. There is an issue with getName() and APC-enabled PHP versions.

The class ReflectionType does not exist. Is this class maybe located in a folder that is not analyzed, or in a newer version of your dependencies than listed in your composer.lock/composer.json?

$argument is not used, you could remove the assignment.
