It seems like $parent defined by \Deployer\Deployer::get()->config on line 23 can also be of type array<string,string|array<integer,string>|boolean|null,{"log_file":"string|array<integer,string>|boolean|null"}>; however, Deployer\Configuration\Configuration::__construct() does only seem to accept null|object<Deployer\Configuration\Configuration>, maybe add an additional type check?
