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

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));

On doing this it's giving below error

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

Don't know how to typecast Function to IRuleTarget or How to convert function to IRuleTarget object

Have you tried namespacing or adding a prefix to your function name? That error sounds like it comes up if there is another lambda function with the same name in the same stack.
