Java 当Kinesis consumer运行并显示错误时，找不到DynamoDB表；无法对不存在的表执行操作“；论地方环境

我已经创建了一个在主函数中运行的运动生产者，该函数将数据放入运动流中，稍后我将其称为运动消费者。我调试了代码，了解到kinesis需要dynamodb来保存租约信息。第一次创建表时，但当我尝试从kinesis获取数据时，它调用dynamodb表并显示错误：

当我尝试从CLI运行以下命令时： “>aws dynamodb描述表--端点urlhttp://localhost:8042 --表名“测试表”

我得到的答复如下： “调用可描述操作时出错（ResourceNotFoundException）：无法对不存在的表执行操作”

我认为这是我的代码试图解析的错误，但无法解析，因为它需要布尔值、null值或json值

我不知道这里发生了什么。

嗨！您能确认数据库在端口8042本地可用吗？
