错误

我尝试通过 AWS 控制台创建堆栈，但在创建 SQS 策略时收到以下错误

检测到 1 个验证错误：“eventSourceArn”处的值“arn:aws:sqs:ap-south-1:219560220147:testlambda”未能满足约束：成员必须满足正则表达式模式：arn:(aws[a-zA -Z0-9-]):([a-zA-Z0-9-])+:([az]{2}((-gov)|(-iso(b?)))?-[ az]+-\d{1})?:(\d{12})?:(.) （服务：AWSLambda；状态代码：400；错误代码：ValidationException；请求 ID：9a86cb1e-49e4- 490d-9e48-fd93aa8d81dd)

CloudFormation Console Error

我已经提交了documentation ，但不知道问题出在哪里？有什么想法吗？

Answer 1

从EventSourceArn 中删除空格。

改变

"LESM34AJN": {
    "Type": "AWS::Lambda::EventSourceMapping",
    "Properties": {
        "EventSourceArn":"  arn:aws:sqs:ap-south-1:219560220147:testlambda",
        "FunctionName": {
    "Fn::GetAtt": [
        "myfunction",
        "Arn"
    ]
},

到

"LESM34AJN": {
    "Type": "AWS::Lambda::EventSourceMapping",
    "Properties": {
        "EventSourceArn":"arn:aws:sqs:ap-south-1:219560220147:testlambda",
        "FunctionName": {
    "Fn::GetAtt": [
        "myfunction",
        "Arn"
    ]
},
