WIX API提取到转发器

Question

我在将wix API提取的数据填充到中继器时遇到问题，尽管我确实在这里遵循了一些示例，但出现错误，不确定为什么...

链接到示例：Wix: Populate repeater with external API call

这里是错误：

Wix code SDK error: Each item in the items array must have a member named `_id` which contains a unique value identifying the item.
Wix code SDK Warning: The data that was passed to data contained at least two items with the same ID: . Only the first item was accepted.

我当前的代码

import {getCurrentTemp} from 'backend/serviceModule';

//...

    export function buttonFetch_click(event, $w) {
      getCurrentTemp($w("#emailInput").value)
        .then(CurrentTemp => {
          // add an _id property to each  object
          CurrentTemp.forEach(item => item._id = item.id)
          // feed the data to the repeater
          $w('#repeater1').data = CurrentTemp;
        } );
    }

    export function repeater1_itemReady($item, itemData, index) {
      $item("#textResults").text = "Name: " + itemData.Title + "\n"
        + "Symbol: " + itemData.BreachDate + "\n"
        + "Rank: " + itemData.Description + "\n"
        + "Price (USD): " + itemData.DataClasses;
    }
