object mapping for [requestParameters.items] tried to parse field [null] as object, but found a concrete value

[Yuta-Kuma]

es-loaderのバージョン2.9.0で発生いたしました。 CloudTrailのログを取り込む際にrequestParameters.itemsが定義されていないためエラーとなっているようです。 eventSource:[dynamodb.amazonaws.com] eventName:PutItem 以下サンプルコードです。

{
    "eventVersion":"1.08",
    "userIdentity":{
        "type":"AssumedRole",
        "principalId":"dummy",
        "arn":"dummy",
        "accountId":"dummy",
        "accessKeyId":"dummy",
        "sessionContext":{
            "sessionIssuer":{
                "type":"Role",
                "principalId":"dummy",
                "arn":"dummy",
                "accountId":"dummy",
                "userName":"dummy"
            },
            "attributes":{
                "creationDate":"2023-04-27T12:18:38Z",
                "mfaAuthenticated":"false"
            }
        }
    },
