Exception when triggering Lambda based API from Cloudwatch Events

*To help us debug your issue fill in the basic information below using the options provided*

*Serverless Java Container version*: `1.5.1`

*Implementations:* `Spring Boot 2`

*Framework version:* `SpringBoot 2.2.6.RELEASE`

*Frontend service:* `AWS Cloudwatch Events`

*Deployment method:* `Console`

## Scenario
I'm trying to schedule a trigger for an API which I have written in Java and deployed in Lambda. Another purpose of this to avoid the cold start as I'm not using provisioned concurrency for my Lambda.
I'm not sure what event to pass so that my API gets triggered properly

## Expected behavior
I expect the API endpoint to be hit at a specific time and it should do what is implemented

## Actual behavior
Since I don't know what even to pass to my trigger so I'm gettings exceptions in my lambda cloudwatch logs

## Steps to reproduce
No code sample required, just create any Java-based Spring boot API on lambda and attach a scheduled cloudwatch event to it.
It will give exceptions in the cloudwatch logs.

2020-07-22 18:17:04.935 ERROR 1 --- [ main] c.a.s.proxy.AwsProxyExceptionHandler : Called exception handler for:
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "id" (class com.amazonaws.serverless.proxy.model.HttpApiV2ProxyRequest), not marked as ignorable (12 known properties: "requestContext", "rawQueryString", "body", "queryStringParameters", "isBase64Encoded", "routeKey", "version", "stageVariables", "rawPath", "cookies", "headers", "pathParameters"])

```

Comece pela falha de desserialização registrada de HttpApiV2ProxyRequest e compare o payload do evento agendado do AWS CloudWatch com o formato de request esperado pela integração Java Spring Boot Lambda. Está concluído quando uma invocação agendada não gerar mais a exceção relatada e o comportamento pretendido da API ocorrer.
