$schema is always a sub-type of Swaggest\JsonSchema\Structure\ObjectItemContract.

            $refs = $schema->getFromRefs();
            if ($refs !== null) {
                foreach ($refs as $ref) {
                    if (substr($schemaPointer, 0, strlen($ref)) === $ref) {

It seems like $schemaPointer can also be of type null; however, parameter $string of substr() does only seem to accept string, maybe add an additional type check?

                        $schemaPointer = substr($schemaPointer, strlen($ref));
                    }
                }
            }
        }

            return $schema;
        }
