imessage 扩展应用程序组对话发送在第一次运行时失败

如何解决imessage 扩展应用程序组对话发送在第一次运行时失败

我有一个 imessage 扩展应用程序，除了第一次发送到群组之外，它运行良好。
iOS 14.4 多设备 8、8plus、10... Xcode 12.4

代码直接从发送闭包（成功）到 didResignActive。该应用程序应该保持活动状态。任何地方都没有解雇。我已经调试了连接的设备并逐步执行了代码，它直接从日志行转到 didResignActive。

如果我在同一组中再次启动该应用程序，它就可以正常工作。仅当我开始新的群组对话，然后单击托盘中的应用程序并调用发送时，该应用程序才会失败。

注意：这只发生在组发送中，并且仅在第一次创建组时发生。

       thisConversation.send(message) { error in
            if let error = error {
                os_log("submitMessage(%@): initial send error: %@",log: .default,type: .debug,type,error.localizedDescription)
            } else {
                os_log("submitMessage(%@): initial send success!",type)
            }
        }

解决方法

编辑： 只是更新... 我被告知要为此提交错误报告（我做了）。

我还提供了一个演示如何重现错误的视频。

这是支持人员发回的消息...

嗨，

感谢您联系 Apple 开发者技术支持 (DTS)。

DTS 无法为反馈 ID #FB9049862 提供解决方法；它 仍在调查中。请继续通过以下方式跟踪问题 错误报告。 ...

我能够创建一个重现这个问题的测试应用程序，我认为用最少的代码来演示。希望这能带来解决方案！
