Multi tab datatable doesn't display data

Nazanin_eb

I have created multi tab datatable, but the table doesn't show data. I debugged and data in Ajax success function is ok but it doesn't display in table.

Your test case is showing numerous browser console errors.

How can the server side code be tested? I have controller action in .net core project.

 public IActionResult GetCategoryById(int id, int languageId = 0)
        {
            var categoryViewModel = _categoryRepository.GetCategory(id, languageId);
            return Json(new { data = categoryViewModel });
        }

        [HttpGet]
        public IActionResult Edit(int id)
        {
            ViewData["categoryId"] = id;

            return View();
        }

The remaining errors are due to the url used in the Ajax section.
