What happened

path is org/apache/eventmesh/runtime/core/protocol/http/processor/BatchSendMessageProcessor.java

i think this is a bug when i read code of master branch. This will cause the batch send of events to fail.

            if (eventData != null || StringUtils.isBlank(batchId)
                    || StringUtils.isBlank(producerGroup)
                    || eventSize != eventList.size()) {
                responseEventMeshCommand = asyncContext.getRequest().createHttpCommandResponse(
                        sendMessageBatchResponseHeader,
                        SendMessageBatchResponseBody.buildBody(EventMeshRetCode.EVENTMESH_PROTOCOL_BODY_ERR.getRetCode(),
                                EventMeshRetCode.EVENTMESH_PROTOCOL_BODY_ERR.getErrMsg()));
                asyncContext.onComplete(responseEventMeshCommand);
                return;
            }

The validation of eventData should be changed to '==null'.

How to reproduce
