I'm having issues witht the select2

$('#charity_user_id').select2({
    ajax: {
      url: "/get-users",
      dataType: 'get',
      delay: 250,
      data: function (params) {
        return {
          q: params.term, // search term
          page: params.page
        };
      },
      processResults: function (data) {
         return {
             results: data
         };
     },
      cache: true
    },
    minimumInputLength: 4,
  });

My ajax call result is something like this:

[{id: 24941, text: "mail@mail.com"}]

Why is select2 not showing the results? It just says "The results could not be loaded"
