Create doc and pdf return null

[goltra]

Hello, i´m testing demo and it build odf file but not doc and pdf file. I tried setting 100 lines with this code (this is only change i made): for ($i=0; $i<100 ; $i++) { $arrayData[]=['aa','bb','cc']; }

$data = array( 'name' => 'Iván Guardado Castro', 'link' => 'ivanguardado.com', 'visits' => $arrayData );

I make a var_dump to var_dump($docGenerator->create('result/final.doc', $data)); and return NULL (same in pdf test).
