在JSON中返回错误的Laravel令牌错误？

I'm using Dropzone for multiple image uploads. If I get a server error that returns "Whoops, there's been an issue" the on-hover error message for that ajax upload flips out and tries to display the html for the entire page. What I need is for that page to return a json message instead. Is there a way for me to catch any errors that occur on upload failure?

you have to include the CSRF token. Normal jquery ajax can have this appended to header on body request parameter

$.ajax({
     type: "POST",
     url: "file",
     data: { 
        _token: $('input[name="_token"]').val()
     }
}).done(function( msg ) {
    console.log( msg );
});
