It seems like $record can also be of type null; however, parameter $record of fab2s\YaEtl\Transformers\Arrays\ArrayMapRecursiveTransformer::arrayMapRecursive() does only seem to accept array, maybe add an additional type check?

    protected function arrayMapRecursive(array $record): array
    {
        $out = [];
        foreach ($record as $key => $value) {
            $out[$key] = is_array($value) ? $this->arrayMapRecursive($value) : call_user_func($this->mapper, $value);
        }

        return $out;
    }
