        return $this->cleanRawData($rawData, strlen($this->numericPrefix));

It seems like $rawData can also be of type null; however, Chubbyphp\Deserialization\Transformer\UrlEncodedTransformer::cleanRawData() does only seem to accept array, maybe add an additional type check?

    {
        $data = [];
        foreach ($rawData as $rawKey => $value) {
            if (0 !== $numericPrefixLength && 0 === strpos($rawKey, $this->numericPrefix)) {
                $rawSubKey = substr($rawKey, $numericPrefixLength);
                if (is_numeric($rawSubKey)) {
                    $rawKey = $rawSubKey;
                }
            }

            $key = is_numeric($rawKey) ? (int) $rawKey : $rawKey;

            if (is_array($value)) {
                $data[$key] = $this->cleanRawData($value, $numericPrefixLength);
            } else {
                $data[$key] = $value;
            }
        }

        return $data;
    }
