尝试创建 lambda 函数时，cloudformation 失败，并显示错误消息“遇到不支持的属性值”
没有提及不受支持的值，并且我找不到任何不正确的值。所有值均仅使用来自 AWS lambda 云形成模板的值。
此外，对于开发人员，我收到错误，指示安全组是字符串类型，但对于 QA 则没有收到错误。
您能否检查一下导致不受支持的值错误的原因以及如何解决开发环境的安全组相关错误。

最佳答案
找到解决方案。这是环境中的值参数不正确的问题。
已更正以下内容并解决了问题。
"Environment" : {
"Variables" : {
"abcHOST": {
"Fn::FindInMap" : [ "params", {"Ref":"abcVPCNAME"}, "HOSTNAME" ]
}
}
还有其他一些问题。
"S3Key" : "/lambda/abc_S3.zip",
应该是
"S3Key" : "lambda/abc_S3.zip",
Deadletterconfig 参数也需要更改。
Current Value:
"DeadLetterConfig" : { "Fn::FindInMap" : [ "params", {"Ref":"abcVPCNAME"}, "TicketSNS" ]},
Correct Value:
"DeadLetterConfig" : {
"TargetArn" : { "Fn::FindInMap" : [ "params", {"Ref":"abcVPCNAME"}, "TicketSNS" ]}
},
在完成上述所有更改后，CFT 开始工作。
