vc-data-source中entities中使用响应式对象进行更新报错

[zyg-admin]

vc-data-source中entities中使用响应式对象，当定时通过接口获取数据进行全量更新时，有时会出现某个entity的id重复报错，但是获取的数据中的编号是没有重复的
报错信息：xxxx already exists in this collection
而且这个错误也不是必现，有一定几率触发，请问该如何解决呢？万分感谢！
原因应该是entities的长度没有变化，但是数据的顺序发生了改变，导致了先移除了另一个id，再添加当前id，但是当前的id已经存在了

unwatchFns.push(
watch(
() => cloneDeep(props.entities),
(newVal, oldVal) => {
if (!vcInstance.mounted) {
return
}
const datasource = vcInstance.cesiumObject as Cesium.DataSource

    if (newVal.length === oldVal.length) {
      // 视为修改操作
      // Treated as modified
      const modifies: Array<any> = []
      for (let i = 0; i < newVal.length; i++) {
        const options = newVal[i]
        const oldOptions = oldVal[i]

        if (JSON.stringify(options) !== JSON.stringify(oldOptions)) {
          modifies.push({
            newOptions: options,
            oldOptions: oldOptions
          })
        }
      }

      modifies.forEach(v => {
        const modifyEntity = datasource.entities.getById(v.oldOptions.id)
        if (v.oldOptions.id === v.newOptions.id) {
          modifyEntity &&
            Object.keys(v.newOptions).forEach(prop => {
              if (v.oldOptions[prop] !== v.newOptions[prop]) {
                modifyEntity[prop] = commonState.transformProp(prop, v.newOptions[prop])
              }
            })
        } else {
          // 改了 id
          datasource.entities.remove(modifyEntity!)
          const entityOptions = v.newOptions
          addEntities(datasource, [entityOptions])
        }
      })
    } else {
      const addeds: any = differenceBy(newVal, oldVal, 'id')
      const deletes: any = differenceBy(oldVal, newVal, 'id')
      const deletedEntities: Array<Cesium.Entity> = []
      for (let i = 0; i < deletes.length; i++) {
        const deleteEntity = datasource.entities.getById(deletes[i].id)
        deletedEntities.push(deleteEntity!)
      }

      deletedEntities.forEach(v => {
        datasource.entities.remove(v)
      })
      addEntities(datasource, addeds)
    }
  },
  {
    deep: true
  }
)

)

我看了dataSource这段代码，如果props.entities的顺序改变了，是否就会导致重复id的问题
