Hey <@U03EG8MUV60>, it’s a bit tricky to do it right now. Lemme push out an update.

Hey Frank. Wow thanks! looking forward to it.

<@U03EG8MUV60> so I just added support for reusing existing Functions as targets, (haven’t released yet):
```import * as lambda from "aws-cdk-lib/aws-lambda";

new EventBus(stack, "Bus", {
  rules: {
    rule1: {
      pattern: { source: ["myevent"] },
      targets: {
        myTarget: {
          cdk: {
            function: lambda.Function.fromFunctionName(stack, "ITarget", "my-function"),
          },
        },
      },
    },
  },
});```

It works when the imported function is in the same Account/Region as the app.

Do u know if it’s possible to add a target to an EventBus that’s in another account?

This blog post seems to suggest it’s not possible perhaps? <https://aws.amazon.com/blogs/compute/simplifying-cross-account-access-with-amazon-eventbridge-resource-policies/>

Sorry i may have misspoke. The lambda is in another repo, different stack. I know the arn. If the function name works, that is ok because the bus is in the same account

In the cdk eventbus you can create a target with the ‘fromArn’ method and then specify which bus to assign the target to.

ah that makes sense. I will cut a release in a bit.

<@U03EG8MUV60> just released this in v1.2.16, here’s an example <https://docs.serverless-stack.com/constructs/EventBus#using-existing-lambda-functions-as-targets>
