## Example

```ts
declare const rule: events.Rule;
declare const fn: lambda.Function;

rule.addTarget(new targets.LambdaFunction(fn, {
  event: events.RuleTargetInput.fromObject({
    instance: events.EventField.fromPath('$.detail.instance-id'),
    account: events.EventField.account,
  }),
}));
```

## Properties

- `deadLetterQueue`: [IQueue](/cdk/api/v2/docs/aws-cdk-lib.aws_sqs.IQueue.html) — The SQS queue to be used as deadLetterQueue. Check out the [considerations for using a dead-letter queue](https://docs.aws.amazon.com/eventbridge/latest/userguide/rule-dlq.html#dlq-considerations).

  **Default:** no dead-letter queue

  The events not successfully delivered are automatically retried for a specified period of time,
  depending on the retry policy of the target.
  If an event is not delivered before all retry attempts are exhausted, it will be sent to the dead letter queue.

- `event`: [RuleTargetInput](/cdk/api/v2/docs/aws-cdk-lib.aws_events.RuleTargetInput.html) — The event to send to the Lambda.

  **Default:** the entire EventBridge event

  This will be the payload sent to the Lambda Function.

- `maxEventAge`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = Duration.hours(24) — The maximum age of a request that Lambda sends to a function for processing.

  Minimum value of 60.
  Maximum value of 86400.

- `retryAttempts`: number = 185 — The maximum number of times to retry when the function returns an error.

  Minimum value of 0.
  Maximum value of 185.
