新建引擎时，在嵌套函数传递过程 task 释放了，该如何解决。

[iT-Boyer]

(cl-defmethod gts-claude-talk-lasttime ((engine gts-claude-engine) text done fail)
  (with-slots (talkurl auth-key channel) engine
    (setq turl (format talkurl channel (url-hexify-string text)))
    (gts-do-request turl
                    :headers `(("Authorization" . ,(format "Bearer %s" auth-key)))
                    :done done
                    :fail fail)
    ))

(cl-defmethod gts-translate ((engine gts-claude-engine) task rendercb)
  (gts-claude-talk-lasttime engine (oref task text)
                            (lambda ()
                              ;; (with-slots (text) task
                              ;; (message "对话内容：%s" (oref task text))
                              (goto-char (point-min))
                              (let ((time)
                                    (json-object-type 'plist)
                                    (json-array-type 'list))
                                (let ((json-data (json-read)))
                                  (setq time (plist-get json-data :ts))
                                  (message "传递时间戳00 :%s " time)
                                  (gts-update-raw task (buffer-string))
                                  (message "传递时间戳11 :%s " time)
                                  ;; (message " done --:%s " (oref engine talkurl))
                                  ;; (message "fail--:%s" turl)
                                  (subscribe-claude-request engine time (lambda ()
                                                                          (message "完成开始绘制 -- ")
                                                                          (gts-update-raw task (buffer-string))
                                                                          (gts-parse (oref engine parser) task)
                                                                          (funcall rendercb)
                                                                          )
                                                            ))))

                            (lambda (err)
                              (gts-render-fail task
                                (format "获取令牌密钥时出错，请检查您的网络和代理，或稍后重试\n\n%s" err)))))

在gts-claude-talk-lasttime的闭包回调时，运行到这段代码提示 task 为nil

 (gts-update-raw task (buffer-string))
(message "传递时间戳11 :%s " time)

希望能帮忙分析下，是否存在语法的问题。
