在golang中使用CDK将目标添加到CloudWatch事件规则

Question

我是aws的typescript CDK的新手，我正在尝试在typescript中使用CDK部署一个lambda函数，如下所示：

const lambdaFn = new lambda.Function(..);

现在，我正在尝试创建一个需要触发这个lambda函数的事件规则。当我在规则中添加targets部件(如下所示)时，我看到如下所示的错误。

const rule = new events.Rule(
  this,
  'Rule',
  {
    eventPattern: {"source": [ "aws.organizations" ], "detail": { "eventName": [ "CreateAccountResult" ] } },
    targets: [ new targets.LambdaFunction(lambdaFn) ] // <<<--- this line throws exceptions..
  }
);

我看到了异常：

lib/test.ts:26:20 - error TS2322: Type 'LambdaFunction' is not assignable to type 'IRuleTarget'.
  Types of property 'bind' are incompatible.
    Type '(rule: IRule, _id?: string | undefined) => RuleTargetConfig' is not assignable to type '(rule: IRule, id?: string | undefined) => RuleTargetConfig'.
      Types of parameters 'rule' and 'rule' are incompatible.

                                                 ~~~~~~~~

我遗漏了什么？
