# $(…).autocomplete(…).data(…) is undefined JS error

 * I get three JS errors in my JS console from script.js, lines 799, 1002 and 838
 * $(…).autocomplete(…).data(…) is undefined JS error
 * I believe it has to do with this code.
 * The odd thing is, my instagram feed is working fine, however another module on
   my site that uses JS is not working, and I think it’s related to this JS error.

       $.ajax({
               url: ajaxurl,
               dataType: 'json',
               cache: false,
               data: {'action': 'get_stream_names'},
               success: function (data) {
                   if (data) {
                       $('#stream_name').autocomplete({
                           search: function (event, ui) {
                               $(this).removeClass("wait");
                           },

                           return $("<li></li>")
                                   .data("item.autocomplete", item)
                                   .append("<a>" + newText + "</a>")
                                   .appendTo(ul);

 * Apologies, I believe I got the wrong plugin. The plugin folder is called “stream-
   insta”, which I believe is a different one.

 * Hey Jordan,
 * No problem. You are correct, that isn’t our plugin. I wish you speedy resolution
   with your issue.
