    @PostMapping
        @ResponseStatus(HttpStatus.CREATED)
        @PreAuthorize("@messageSecurityService.isAuthorized(#userAuthentication)")
        public void sendMessage(@AuthenticationPrincipal UserAuthentication userAuthentication,
                                @RequestBody SendMessageRequest sendMessageRequest) {
                                              ......
     }

我想编写此端点的测试，但出现以下错误。
