意思是一次请求数据量太大吗？之前用add提交20000+条数据，没报这个错啊。是新加了限制吗？

如果数据量太大怎么add呢？

代码：

console.log('读取数据[记录数=' + recordsLength + '][耗时=' + readMS + '秒]')
  // return
  await db.collection('xxx').add({
    data: data
  }).then(res => {
    if (res.errMsg == 'collection.add:ok') {
      let after = new Date()
      let costMS = (after.getTime() - read.getTime()) / 1000
      console.log('统计成功: [统计月份=' + lastMonthYm + '][记录生成时间=' + nowStr + '][生成记录数量=' + recordsLength + '][耗时=' + costMS + '秒]')
    } else {
      console.log('统计失败:', res)
    }
  })
