我有一個基本的控制器動作：    public function createAction() {        $this->view->disable();        $formData = $this->request->getJsonRawBody();        $user = new Users();        $user->first_name = $formData->first_name;        $user->last_name = $formData->last_name;        $user->email_address = $formData->email_address;        $user->password = $formData->password;        // this prints to my debug log.        $result = $user->save();         AppLogger::$logger->debug(print_r($result, true)); // this does not print.        AppLogger::$logger->debug("oh boy #2"); // this does not print either.        // which seems to tell me that the line above it is problematic,        // but there is no error output from `phalcon serve`        echo Json::encode($result);    }我看到的最接近錯誤的是PHP/Phalcon Error: Closed without sending a request; it was probably just an unused speculative preconnection：這出現在 的輸出中phalcon serve。我phalcon serve在 Windows 上運行 VSCode。
