SyntaxError: Unexpected end of input (jQuery)

Question

I know this is usually an issue of unbalanced parens and curly braces, however after carefully sifting through my syntax, I have, to the best of my ability, confirmed the correct parity of each of these scope delimiters and have no other recourse except to allow my fellow S.O. pundits to take a gander at the following:

$.ajax({
      url: "/application/get_programs_for_center",
      type: "POST",
      data: formdata,
      success: function(response){
       var options = $("#school_application_program_name");
       var result = JSON.parse(response);
       console.log(result);
       $.each(result, function() {
          options.append($("<option />").val(this.id).text(this.name));
        });
      }
  });

N.B. the error is being thrown in the middle of the line var result = JSON.parse(response); specifically immediately after JSON.

It's not in the line, the error is thrown by the called JSON.parse function itself because response is not a valid JSON string. — Bergi

The problem you have is that what you parse isn't JSON.

And the reason it's not JSON, is that the response argument you receive is already parsed from JSON by jQuery. Don't parse it again.

If you parse JSONArray, jQuery will not parse it into Object directly, you have to use JSON.parse(response)

However, if you parse a JSONObject, it will be identified and parse into Object automatically So keep it in mind, that will help you!
