Does anyone already set up a video upload using Laravel 4.2 and DropzoneJS on DigitalOcean?

I just did and everything works fine on my localhost, but when I try to upload a video on my online application (hosted on DigitalOcean), I have the following issues:

file: "/home/forge/default/app/controllers/admin/VideosController.php" line: 45 message: "Call to a member function getClientOriginalName() on null" type: "Symfony\Component\Debug\Exception\FatalErrorException"

This is my code on this line:

˜˜˜

	$file = Input::file('file');

	$video = Video::create([
			'name' => explode('.', ucfirst(strtolower($file->getClientOriginalName())))[0],
			'file' => $file,
			'extension' => $file->getClientOriginalExtension(),
			'size' => $file->getSize(),
		]);

	return count($video->validationErrors) == 0 ? Response::json('success', 200) : Response::json($video->validationErrors->first(), 400);

˜˜˜

Any ideas?

Thanks in advance!
