Spring - When use DELETE with json returns Bad Request

I am developing simple rest api with spring boot. I create users via POST method. And deletes via DELETE. But when i use DELETE with json server returns Bad Request.

creating user:

ubuntu@ubuntu-pc:~$ curl -X POST -H "Content-type: application/json" -d '{"name": "developer", "email": "[email protected]"}' http://localhost:8080/add-user "OK" 

getting users:

ubuntu@ubuntu-pc:~$ curl http://localhost:8080 [{"id":"ff80818176c9b9720176c9bdfd0c0002","name":"developer","email":"[email protected]"}] 

deleting user using json:

ubuntu@ubuntu-pc:~$ curl -X DELETE -H "Content-type: application/json" -d '{"id": "ff80818176c9b9720176c9bdfd0c0002"}' http://localhost:8080/del-id {"timestamp":"2021-01-03T19:47:15.433+00:00","status":400,"error":"Bad Request","message":"","path":"/del-id"} 

deleting user using html queries:

ubuntu@ubuntu-pc:~$ curl -X DELETE http://localhost:8080/del-id?id=ff80818176c9b9720176c9bdfd0c0002 "OK" ubuntu@ubuntu-pc:~$ curl http://localhost:8080 []
