Tesseract OCR for PHP (Image to characters)

I am using Tesseract OCR for PHP and Laravel 5.6, to extract characters from an image, but I do not use the library that I use this .

I put the facade, the code is as follows:

$filePath = public_path() . '/imagenes/text.png';
$dat = (new TesseractOCR($filePath))->run();
dd($dat);

The path of the image is fine but I do not get the letters of the text of the image, I get the following: " " .
