fetchMessage receive some empty message

[sunxiatao]

When consuming messages using Kafka's FetchMessage in a consumer group, each message is followed by an unexpected message with a length of 6 and a value consisting of six \u0000 characters (null characters). These "empty" messages do not exist in the topic, which suggests there may be an issue with how the kafka-go consumer is handling message offsets or fetching messages.
