Subject of the issue

AEP multiple message response is not handled correctly. Response from AEP endpoint contains multiple status code for each message in batch, connector should throw error or send message to dead topic incase of failure based on error tolerance configuration.

"errors.tolerance": "all",
"errors.deadletterqueue.topic.name": "error-topic",
"errors.deadletterqueue.context.headers.enable": "true",
"errors.log.enable": "true"
