有人知道vue3多层级对象数组怎么把新的值覆盖传给他？

Question

channelStatus接口掉过之后会一直报错TypeError: Cannot read properties of undefined (reading 'title')。
接着我的项目就不能切换路由了，报错Uncaught (in promise) TypeError: Cannot read properties of null (reading 'parentNode')

const channelStatus = () => {
      state.list1 = {}
      const params = {}
      proxy.$request
        .get(`/monitor/channelStatus`, {
          params,
        })
        .then((res) => {
          console.log(res.data)
          state.list1 = {
            title: res.data.title,
            barBox: res.data.secureAccessArea,
            barBox2: res.data.powerPrediction,
          }
        })
    }

const channelStatus = () => {
      state.list1 = {
        title: '',
        barBox: {},
        barBox2: {},
      }
      const params = {}
      proxy.$request
        .get(`/monitor/channelStatus`, {
          params,
        })
        .then((res) => {
          let arys = JSON.stringify({
            title: res.data.title,
            barBox: res.data.secureAccessArea,
            barBox2: res.data.powerPrediction,
          })
          arys = JSON.parse(arys)
          state.list1 = {
            ...arys,
          }
        })
    }
