    {
        if (is_array($value)) {
            return array_merge($array, $this->arrayValuesRecursive($value));

It seems like $this->arrayValuesRecursive($value) can also be of type mixed; however, parameter $array2 of array_merge() does only seem to accept null|array, maybe add an additional type check?

        }

        return array_merge($array, [$value]);
    }
