How to parse the error in the json response

API
3

Hi Barry
I am checking multiple people at once so something like
is person A following person Z
is person B following person Z
etc…
The code only gives me response when The first person is following the second, but not when he is not

The code here

         $.ajax({
         dataType: "jsonp",
         jsonp:"callback",
         url: "https://tmi.twitch.tv/group/user/hidemon/chatters",
          success: function viewera(data){

//seeing the result in the console
console.log(data);
//gets the viewers
  $.each(data.data.chatters.viewers, function(i, field) {
      var viewers = field;
      // Check if they are followers!
      
      
            var follow = "https://api.twitch.tv/kraken/users/" + viewers + "/follows/channels/" + userName + "?client_id=xxx";
             $.getJSON(follow, function(resulta){
                 $.each(resulta, function(i2, field2) {
           
                $("#go").append("<p>" + field2 + "</p>");
            
             });        
             });

I did not find anything related to my problem on stackoverflow so I was hoping I can find some help here !
Thank you in advance!
