Can anyone help me fix this. I have hard coded json object which is suppposed to map to my POJO but I'm getting null values in my Spring Controller. I've checked my getters and setters. They seems to be correct. What am i doing wrong here ?

Controller

```
@PostMapping("/dashboard")
public Dashboard getDashboard(@RequestBody PaginationRequest paginationRequest) {
      return topcatService.getDashboard(paginationRequest);
}

```

json

```
 var paginationRequest = { grouping  : e.target.value ,total : "1", currentPage : "1", pageSize : "5"};

```

POJO

```
 public class PaginationRequest {
        private String grouping;
        private String total;
        private String  currentPage;
        private String pageSize;

       //setter/getter
    }

```
