当我想使用cloudformation创建堆栈时出现以下错误：
The following resource(s) failed to create: [ApiSyncLogsPost]. . Rollback requested by user.
CREATE_FAILED AWS::ApiGateway::Method ApiSyncLogsPost Integrations of type 'AWS_PROXY' currently only supports Lambda function and Firehose stream invocations. (Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException; Request ID: 8bff48b0-93e4-11e8-a183-5de2b976f282)
我在Google上没有发现与此错误相关的任何信息，当我搜索它时，我得到了很多AWS cloudformation文档。
我认为正在发生的情况是ApiSyncLogsPost资源的定义不正确，但是我在互联网上发现的示例与此类似。
要解决该错误需要更改什么？

答案 0 :(得分：5)
该错误是由于ApiSyncLogsPost资源中Integration.Uri的值不正确引起的。 Uri的格式应为：
arn:aws:apigateway:{region}:{subdomain.service|service}:path|action/{service_api}
示例：
arn:aws:apigateway:eu-west-1:lambda:path/2015-03-31/functions/arn:aws:lambda:eu-west-1:012345678901:function:MyLambda/invocations
在您的情况下，末尾的字符串"/synclogs"实际上应该是"/invocations"
以下Integration.Uri的{{1}}应该可以解决此问题：
ApiSyncLogsPost
