Custom JSON to populate a Datatable

Im creating a DataTable from an Ajax json.

resultTable = $('#changeTable').DataTable({
            "order": [[0, "desc"]],
            "pageLength": 50,
            "scrollX": true,
            "lengthMenu":[[50,100,250, -1], [50, 100, 250, "All"]],
            "dom":'<"toolbar">ltipr', //write ltfipr to show a search bar
            "ajax":{
                url:"api/changes",
                "dataType":"json",
                timeout:15000
            }
    });

The DataTables creates but it shows an error:

DataTables warning: table id=changeTable - Requested unknown parameter '0' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4

My JSON Looks like the following

{"data":
    [
       {"id":1,
        "createdDate":"Apr 18, 2018 4:10:58 PM",
        "source":"manual upload",
        "emailId":"manual upload",
        "attachmentId":"manual upload",
        ...,},
       {next objet}]}

Such JSON object is created in my Java controller:

@RequestMapping(value = "/api/changes", method = RequestMethod.GET, produces = "application/json")
    @ResponseBody
    public String getChanges(){
        Optional<List<PriceChange>> priceChangeList = pcService.findAllPriceChanges();
        JsonObject result = new JsonObject();
        if (priceChangeList.isPresent()) {
            result.add("data", new Gson().toJsonTree(priceChangeList.get()));
            return  result.toString();
        }
        return null;

    }

I don know how to use this information with the dataSrc property to make it work for the DataTable. Any Ideas?

You just need to define columns for the table. If you have 

<table id="changeTable"></table>

add this to your DataTables options :

resultTable = $('#changeTable').DataTable({
  ...,
  columns: [
     { data: 'id', title: 'id' },
     { data: 'createdDate', title: 'createdDate' },
     { data: 'source', title: 'source' },
     { data: 'emailId', title: 'emailId' },
     { data: 'attachmentId', title: 'attachmentId' }
   ]
})

If ypu have specifed a <thead> section you can skip the title's.
