我在 AWS lambda 上有一个托管 MS Teams 机器人的无服务器后端。此机器人的状态存储在 CosmosDB 中。当我多次触发我的机器人时，我现在遇到了问题。我已经在 GitHub 上开过一张票，但不确定这是否应该被视为一个错误，或者更多是我可以修复的问题。该问题可以在这里找到：https ://github.com/microsoft/botbuilder-python/issues/1909
语境
当我连续多次触发我的机器人时，将激活多个 lambda 函数。然后这些函数将尝试并行处理这些消息。问题是他们都尝试更新 CosmosDb 中的机器人状态，这会导致 412 Precondition failed 错误。
我发现了这个问题：https ://github.com/microsoft/botframework-sdk/issues/3383简要介绍了它，但在 python 中没有。这是一个错误，或者如果不是，如何解决？从这个问题（见链接），我知道设置e_tag为*可以解决这个问题，但我无法弄清楚如何使用机器人构建器框架来完成。
是否不可能在无服务器后端有效地运行团队机器人？
错误信息：（抱歉格式错误）
