#1912 readAsDataURL function not found on file upload

[Jose Roman Bilbao]

When trying to submit files from HTMLInput a fatal error is obtained. The web is using Dropzone.js

I cannot provide a test url as the web causing this is three to four steps behind the starting point and requires filling a lot of forms.

This code:

File fileToUpload = new File("C:\firma.jpg");
HtmlFileInput fileUploader = (HtmlFileInput) currentPage.getFirstByXPath("//input[@type='file']"); fileUploader.setFiles(fileToUpload); --> This causes the exception

Exception message:

GRAVE: Job run failed with unexpected RuntimeException: TypeError: Cannot find function readAsDataURL in object [object FileReader]. (https://static.milanuncios.com/js/fotos/dropzone.4.2.0.min.js#1)
