It seems like $path defined by $path on line 43 can also be of type object<phpDocumentor\Path>; however, phpDocumentor\Parser\SpecificationFactory::inPath() does only seem to accept string, maybe add an additional type check?

        }

        $ignoreSpec = null;
        foreach ($ignore['paths'] ?? [] as $path) {

The expression $ignore['paths'] ?? array() of type object<phpDocumentor\Path>|string|array is not guaranteed to be traversable. How about adding an additional type check?
