通过云形式失败创建GatewayAuthorizer-并发修改

Question

我正在编写一个CF模板，其中包含一个带有某些端点的API网关，一个带有关联域和客户端的Cognito用户池，IDP和授权器。网关以及池和IDP成功创建。

但是，授权者并未成功创建。它本质上是在create_in_progress中长期存在的，然后在ConcandException /并发修改异常中失败：

{
    ... events ...
    "eventTime": "2022-06-24T18:49:48Z",
    "eventSource": "apigateway.amazonaws.com",
    "eventName": "CreateAuthorizer",
    "awsRegion": "eu-west-1",
    "sourceIPAddress": "cloudformation.amazonaws.com",
    "userAgent": "cloudformation.amazonaws.com",
    "errorCode": "ConflictException",
    "requestParameters": {
        "identitySource": [
            "$request.header.Authorization"
        ],
        "name": "JwtCognitoAuthorizer",
        "jwtConfiguration": {
            "audience": [
                "3t5s..."
            ],
            "issuer": "https://cognito-idp.eu-west-1:223249055027.amazonaws.com/eu-west-1_orEMePYWZ"
        },
        "authorizerType": "JWT",
        "apiId": "us0ekpcxhc"
    },
    "responseElements": {
        "message": "Unable to complete operation due to concurrent modification. Please try again later."
    },
...
}

我正在为授权者使用以下CF片段：

  APIGatewayAuthorizer:
    Type: AWS::ApiGatewayV2::Authorizer
    Properties:
      ApiId: !Ref apiGateway
      AuthorizerType: JWT
      IdentitySource:
        - "$request.header.Authorization"
      JwtConfiguration:
        Audience:
          - !Ref UserPoolClient
        Issuer: !Sub 'https://cognito-idp.${AWS::Region}:${AWS::AccountId}.amazonaws.com/${UserPool}'
      Name: JwtCognitoAuthorizer

并发修改使其听起来像某种依赖性问题（也许是在创建事物以错误的顺序？）但是我认为云形式本身是纠正的。

我看不到任何其他解决此问题的问题 - 任何建议或链接都​​赞赏。

谢谢
