通過 CDK 關閉 Stepfunctions 的默認重試策略

Question

我使用以下代碼創建了一台 state 機器

const taskState2 = new tasks.LambdaInvoke(this, 'call 2nd lambda', {
      lambdaFunction: secondlambda,
      payloadResponseOnly: true
    });


    const taskState1 = new tasks.LambdaInvoke(this, 'Call 1st lambda', {
      lambdaFunction: first_lambda,
      payloadResponseOnly: true
    });

    //taskState1.addRetry(retryPolicy).next(taskState2);
     taskState1.next(taskState2);

    const mapstate = new sfn.Map(this, 'MapStateStepLambda', {
      itemsPath: '$.StepLambdaInput',
      maxConcurrency: 10,
    }).iterator(taskState1);

    const stateMachine = new sfn.StateMachine(this, 'MyStateMachine', {
      definition: mapstate,
      stateMachineName: `StateMachine`
    });

但是當我部署它時，它會自動附加重試策略

"Call 1st lambda": {
            "Next": "Call 2nd lambda",
            "Retry": [
              {
                "ErrorEquals": [
                  "Lambda.ServiceException",
                  "Lambda.AWSLambdaException",
                  "Lambda.SdkClientException"
                ],
                "IntervalSeconds": 2,
                "MaxAttempts": 6,
                "BackoffRate": 2
              }
            ],
            "Type": "Task",
            "Resource": "**"
          },

當我通過 cdk taskstate1.addRetryPolicy(mypolicy)附加一些用戶定義的重試策略時，我仍然可以在部署后看到默認策略。 如何刪除默認重試策略或使用 cdk 編輯默認重試策略。
