Not getting records for S3Event (version 2.1)

[konstantinj]

I have issues getting my s3 event to run in my tests. I've captured this event from an actual file uploaded to my bucket.
Using the event from #187 is working for me - I get 1 record out of it.

Why is my event no working?

    @ParameterizedTest
    @Event(value = "test_s3_event.json", type = S3Event.class)
    public void testHandleRequest(S3Event s3Event) throws Exception {
        log.info("records: {}", String.valueOf(s3Event.getRecords().size()));
        ...

I just faced this issue myself. The problem is not a bug in your code, but that the request data does not match the API. records is required to be capitalized:

{
  "Records": [
    {
      "awsRegion": "eu-central-1",
      ...
}
