问题描述
我创建了一个在主要功能中运行的运动产生器，该函数将数据放入运动流中，随后我称其为“消费者”。我调试了代码，并了解运动学需要dynamodb来保存租约信息。第一次创建表时，但是当我尝试从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 describe-table --endpoint-url http：// localhost：8042 --table-name测试表”
我得到以下答复： “调用DescribeTable操作时发生错误（ResourceNotFoundException）：无法对不存在的表进行操作”
我认为这是我的代码尝试解析但无法解析的错误，因为它期望布尔值，null或json值。
我不确定这里发生了什么。
