Using JSON(Javascript Object Notation) datasource send data from .Net Core

Hi,

I create a list from person class that using .Net Core 5.0. and send to report but fastreport consists of a single line from the first element of the list.

      List<Person> data = GetDummyData();
      Report report = new Report();
      report.Load("C:\\Users\\testyazilim\\Desktop\\PersonJsonTest.frx");
      report.RegisterData(data, "JSON.item");
      report.Prepare();

The json format I use is as follows; and json schema is created automatically.

{
 "Id": {
  "type": "integer"
 },
 "Name": {
  "type": "string"
 },
 "Surname": {
  "type": "string"
 },
 "Age": {
  "type": "integer"
 }
}

the report is generated successfully but only from a single line, although I use a table in ".frx" report. I used many different versions of json, but the result was the same.

I use FastReport Community.
