What is wrong with this Java Spring controller method returning 204?

@DeleteMapping("/item/{id}")
public ResponseEntity deleteItem(@PathVariable String id) {
    // delete logic
    return ResponseEntity.noContent().body("Deleted");
}

APathVariable annotation is missing

BResponseEntity.noContent() cannot have a body

CDeleteMapping should return 200 instead
