On adding target(LambdaFunction) to Event Rule in AWS-CDK in java giving error: There is already a Construct with name lambda_name in stack

Question

Function lambdaFun =
            Function.Builder.create(this, LAMBDA_NAME)
                    .runtime(Runtime.JAVA_11)
                    .code(LambdaCode)
                    .functionName(LAMBDA_NAME)
                    .handler("handler_xyz")
                    .role(role)
                    .memorySize(3008)
                    .timeout(Duration.minutes(15))
                    .environment(LAMBDA_ENV)
                    .build();
    Rule rule =
                Rule.Builder.create(this, CWE_NAME)
                        .schedule(Schedule.rate(Duration.seconds(60)))
                        .description("CloudWatch Event")
                        .build();

    rule.addTarget(new LambdaFunction(lambdaFun));

执行此操作时出现以下错误

Caused by: software.amazon.jsii.JsiiException: There is already a Construct with name 'lambda-name' in Stack

不知道如何将函数类型转换为 IRuleTarget 或如何将函数转换为 IRuleTarget 对象

Answer 1

您是否尝试过命名空间或为您的函数名称添加前缀？如果在同一个堆栈中有另一个同名的 lambda 函数，那么这个错误听起来好像会出现。
