$kernel is of type Symfony\Component\HttpKernel\KernelInterface, but the property $kernel was declared to be of type Symfony\Component\HttpKernel\Kernel. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?

The variable $config seems to never exist and therefore isset should always be false.
