Laravel uploaded file not being read properly

I am printing the contents of a simple file upload request in Laravel 5.6 and for some strange reason the file doesn't have any information attached to it.

public function uploadDocument(Request $request)
{
    $file = $request->file('file');
    dd($file);
}

It prints the following:

Which I found very strange as it has detected a file but doesn't have any file info. I have tried with multiple file types and get the same error.

I am using Laravel 5.6.23 and PHP version 7.1.9 on my local WAMP server

Anyone know why this is happening?
