use Symfony\Component\Yaml\Yaml;

The type Symfony\Component\Yaml\Yaml was not found. Maybe you did not declare it correctly or list all dependencies?

It seems like octdec($permissions) can also be of type double; however, parameter $permissions of mkdir() does only seem to accept integer, maybe add an additional type check?

Are you sure print_r($action, true) of type string|true can be used in concatenation?
