amazon-web-services - AWS sam部署失败: Waiter ChangeSetCreateComplete failed: Max attempts exceeded

Question

刚刚向我的堆栈的 template.yaml 添加了一个 DynamoDB 表。运行 aws deploy 卡住一段时间并显示消息正在等待创建变更集..几分钟后失败了

File "/usr/local/Cellar/aws-sam-cli/1.26.0/libexec/lib/python3.8/site-packages/samcli/lib/deploy/deployer.py", line 295, in wait_for_changesetreason = resp["StatusReason"]KeyError: 'StatusReason'

我不确定我缺少什么，我相信该用户的 IAM 也拥有所有必需的权限。我对 AWS 非常陌生，因此我们将不胜感激。

我的 template.yaml 是

您的 template.yml 中有几个错误。

1. 您的 Dynamo 表类型在 Dynamo 之后缺少第二个冒号。

2. Policy 属性需要位于您的 Lambda 上，而不是您的表上。您想要让 Lambda 函数访问您的表，而不是您的表本身，这是没有意义的。

3. GlobalSecondaryIndexes 是对象列表。您缺少指示列表开始的破折号。
