我们正在尝试在SAM模板中创建AWS：：WAFv2：：IPSet。
WhitelistedIPAddressesIPSet:
Type: AWS::WAFv2::IPSet
Properties:
Description: 'Merchant IPs'
Scope: REGIONAL
IPAddressVersion: IPV4
Addresses: [0.0.0.0/32, 0.0.10.0/32]
IP 集的创建成功完成。 创建 AWS：：WAFv2：：WebACLAssociation。
WAFApiAssociation:
Type: AWS::WAFv2::WebACLAssociation
DependsOn:
- ApiGateway
- WAFWebAcl
Properties:
ResourceArn: !Sub 'arn:aws:apigateway:${AWS::Region}::/restapis/${ApiGateway}/stages/${EnvType}'
WebACLArn: !GetAtt WAFWebAcl.Arn
CloudFormation 失败并执行回滚。显示的错误如下：
Resource handler returned
ion message: "AWS WAF couldn?t
perform the operation
because your resource
doesn?t exist. (Service:
Wafv2, Status Code: 400,
Request ID: e337720a-e32c-
4c29-acde-1896855405c9,
Extended Request ID:
null)" (RequestToken: f24d
0488-3016-4030-3a3b-bbb246
66f130, HandlerErrorCode:
NotFound)
我们尝试了不同的格式化IP集的SAM模板，看看这是否会导致问题，但没有任何成功。
有人可以分享对这个问题的一些有用的见解吗？
A) 如果你的资源已经直接依赖于这些其他资源，你不需要DependsOn。在这种情况下，它确实如此，因此您可以删除此属性。
B) 您需要在此处共享整个堆栈，而不仅仅是共享的内容，因为您的 APIGW 配置可能存在问题。由于创建失败，因此可能会出现此后续问题。
创建 APIGW 是不够的，您需要确保在创建 APIGW阶段后实际附加 WAF，而不仅仅是 APIGW。在这种情况下，将ResourceArn替换为引用APIGW Stage的。(此外，您可能需要等待阶段部署完成。
