action :在向codepipeline添加代码部署操作时出错(jsii.errors.JSIIError:无法读取未定义的属性“区域”)

Question

如果我移除代码部署阶段，codepipeline将创建并执行Source (GitHub)和Build (坞映像到ECR)阶段。在本例中，我还创建了一个新的ECS集群，它将被创建以及预期的服务。

--这是代码的一部分：

fargate_service = ecs_patterns.ApplicationLoadBalancedFargateService(self, parms["ecs_fargate_service"],
            cluster = ecs_cluster,
            task_definition = task_definition,
            public_load_balancer = True,
            desired_count = 2,
            listener_port = 80,
            min_healthy_percent = 100,
            max_healthy_percent = 200,
            assign_public_ip = False,                
        )

deploy_action = codepipeline_actions.EcsDeployAction(
            action_name = 'DeployAction',
            service = fargate_service,
            image_file = codepipeline.ArtifactPath(build_output, 'imagedefinitions.json')
        )

pipeline = codepipeline.Pipeline(self, "CodePipeline",
            pipeline_name=parms["pipeline_name"]+"test",
            cross_account_keys = False,
            stages=[
                codepipeline.StageProps(stage_name="Source", actions=[source_action]),
                codepipeline.StageProps(stage_name="Build", actions=[build_action]),
                codepipeline.StageProps(stage_name="Deploy-to-ECS", actions=[deploy_action])
            ]
        )

如果删除这一行codepipeline.StageProps(stage_name="Deploy-to-ECS"，actions=deploy_action)，则没有错误，堆栈也能工作。

我已经尝试过以下测试：

引用现有的ECS集群创建

• ，在本例中，没有错误，部署阶段以文档的形式工作，并且无法将该区域指定给Codepipeline项目。

这是错误

      at /tmp/tmpg46d0z4s/lib/program.js:8367:58

The above exception was the direct cause of the following exception:

    pipeline = EcsCicdStack(main_stack, "Pipeline-"+parms["stage"], vpc=vpc_stack.vpc, parms=parms)

    raise JSIIError(resp.error) from JavaScriptError(resp.stack)
jsii.errors.JSIIError: Cannot read property 'region' of undefined

这是我的环境的配置：

CDK CLI Version : 1.120.0 (build 6c15150)
Framework Version: 1.120.0 (build 6c15150)
Node.js Version: v16.8.0
OS : Ubuntu 20.04 LTS
Language (Version): Python 3.8.2

如果你能给我一个关于在哪里看的想法，我会非常感激的。

提前感谢！

致以问候。

这是因为EcsDeployAction在service参数中接受aws_ecs.IBaseService，并且传递一个ecs_patterns.ApplicationLoadBalancedFargateService。

若要访问实际的ECS服务结构，请传递fargate_service.service。
