amazon-web-services - Localstack：函数已经存在/ResourceConflictException

Question

我部署到在 Docker 中运行的 localstack（通过 进行部署serverless-localstack）每次都失败。使用 0.11.1 版本，它在 3-5 次尝试后工作（没有更改任何内容），并且使用最新版本，将整个堆栈部署到 localstack 没有任何变化。我的 localstack docker 镜像是最新的。

当其余的被注释掉时，单独部署一个或两个函数是可行的。即使我将所有函数的处理程序更改为像一些无服务器示例中的简单处理程序，它也可以工作。因此，随着包大小的增加，错误似乎出现了。

我的第一个猜测是部署时会出现一些超时，因为完整的包大小对于八个功能来说相对较大，并且部署需要很长时间。另一个观察：当错误出现时，有 1-2 个函数和资源/流已经部署但无法访问。试图为 docker 提供更多资源，但这也无济于事。

来自本地堆栈的错误：
