iview TimePicker 时间验证问题

1.选择时间范围的时候

//此处是循环表单，v-for = item in objArr

objArr: [
        {
          id: 1,
          pattern: "白天模式",
          upTime: "08:00",
          downTime: "18:00",
          notificationMethod: 1,
          modelUrgency: ["1", "2", "3", "4"],
          time: ["08:00", "18:00"],
        },
        {
          id: 2,
          pattern: "夜间模式",
          upTime: "18:01",
          downTime: "07:59",
          notificationMethod: 2,
          modelUrgency: ["3", "4"],
          time: ["18:01", "07:59"],
        },
      ],

<FormItem
          label="模式时间:"
          :prop="`data[${index}].time`"
          :rules="ruleValidate.time"
        >
          <TimePicker
            type="timerange"
            format="HH:mm"
            placeholder="选择时间"
            separator="~"
            v-model="item.time"
            @on-change="changeTime(index, $event)"
          ></TimePicker>
        </FormItem>

//验证rules
time: [
          {
            required: true,
            type: "date",
            // message: "请选择时间",
            validator: validateTime,
            trigger: "change",
          },
        ],

//验证方法 validateTime

const validateTime = (rule, value, callback, index) => {
      // if (!value) {
      //   return callback(new Error("请选择时间"));
      // } else {
      //   callback();
      // }
      //时间为数组处理-time
      if (!value) {
        return callback(new Error("请选择时间"));
      } else {
        //时间为数组处理
        // console.log("value11111", value);
        value.map((item) => {
          if (!item) {
            return callback(new Error("请选择时间"));
          }
        });
        callback();
      }
    };

2.一般选择的时候

<FormItem
          label="模式开始时间:"
          :prop="`data[${index}].upTime`"
          :rules="ruleValidate.upTime"
        >
          <TimePicker
            type="time"
            format="HH:mm"
            placeholder="选择时间"
            clearable
            v-model="item.upTime"
          ></TimePicker>
        </FormItem>

        <FormItem
          label="模式结束时间:"
          :prop="`data[${index}].downTime`"
          :rules="ruleValidate.downTime"
        >
          <TimePicker
            type="time"
            format="HH:mm"
            placeholder="选择时间"
            clearable
            v-model="item.downTime"
          ></TimePicker>
        </FormItem>

 const validateTime = (rule, value, callback, index) => {
      if (!value) {
        return callback(new Error("请选择时间"));
      } else {
        callback();
      }
      //时间为数组处理-time
      // if (!value) {
      //   return callback(new Error("请选择时间"));
      // } else {
      //   //时间为数组处理
      //   // console.log("value11111", value);
      //   value.map((item) => {
      //     if (!item) {
      //       return callback(new Error("请选择时间"));
      //     }
      //   });
      //   callback();
      // }
    };

 upTime: [
          {
            required: true,
            type: "date",
            // message: "请选择时间",
            validator: validateTime,
            trigger: "change",
          },
        ],
        downTime: [
          {
            required: true,
            type: "date",
            // message: "请选择时间",
            validator: validateTime,
            trigger: "change",
          },
        ],
