LocalStack 无法通过 Java 中的 AWS SES SDK 模拟发送电子邮件端点

Question

我正在使用 LocalStack 模拟 AWS SES 进行测试。我正在通过它的 docker 映像使用 LocalStack。我在创建 AWS SES 客户端期间通过覆盖它的端点来模拟 AWS：

AmazonSimpleEmailService client = AmazonSimpleEmailServiceClientBuilder.standard()
            .withEndpointConfiguration(new EndpointConfiguration(awsEndpoint, region))
            .withCredentials(awsCredentials)
            .build();

在创建身份、列出和发送电子邮件时，AWS CLI（至少对于 SES）与 LocalStack（通过通过 --endpoint-url 参数为其提供 LocalStack 的端点）正常工作。但是，当通过基于 Java 的 AWS SES 开发工具包以编程方式命中时，基于发送电子邮件的开发工具包调用会失败。每当进行此类调用时，LocalStack 都会抛出以下错误：

我不确定究竟是什么导致了错误。请注意，相同的基于发送电子邮件的 SDK 调用与真正的 AWS 完美配合。这是我困惑和怀疑的根源：为什么 LocalStack 会以这种方式表现？它完美地模拟了通过 AWS CLI 发出的发送电子邮件调用，但使用基于 AWS SES 开发工具包的调用却无法做到这一点。我正在使用 AWS 的 SES 版本 1 开发工具包。希望大家能帮我解答一下我的这个疑惑。

我在 localstack 上遇到了同样的问题：0.12.6 升级到 0.14.3 现在可以正常工作了。
