我在尝试使用kafka主题中的数据时遇到了unlimited循环，注意到highwateroffset显示了最新的数字，但值为空，offset=0，partition=0
有人能告诉我出了什么问题吗？
功能
启动时调用的主要函数

function registerUpsertUVIConsumer() {
    const upsertConsumer = kafkaHelper.getConsumer('UVI');

    upsertConsumer.on('message', async (message) => {
      console.log('KAFKA MESSAGE: upsertUVI');
      try {
        await updateUVIToNav(JSON.parse(message.value));
      } catch (error) {
        console.error('ERROR UPDATING UVI TO NAV:', error.message);
      }
    });

    upsertConsumer.on('error', err => {
      upsertConsumer.close(() => {
        console.log('Consumer closed inside error event handler');
      });
      console.log('RETRY in 30s...');
      setTimeout(() => {
        registerUpsertUVIConsumer();
      }, 30000);
    });
  }

获取消费者
main函数中的函数：kafkahelper.getconsumer（'uvi'）

getConsumer(topicName) {
        var kafka = require('kafka-node');
        var client = new kafka.KafkaClient({ kafkaHost: 'localhost:9092' });
        const consumer = new Consumer(

            client,
            [
                { topic: topicName, partition: 0}
            ],
            {
                groupId: 'consumer',
                fromOffset: false,
                autoCommit: true
            }

        );

        return consumer;
    }

示例json数据：偏移量16
示例json数据之一，选择偏移量16（主题中的最后一个偏移量）
