let parentId = ''
    let newMenuTarget: {[id: string]: ItemType} = {}
    while(oldMenus.length) {
      const item = oldMenus.shift() as IModelsGlobal['menu'][number]
      const menuItem: ItemType = {
        key: item.id,
        icon: <i className="anticon">
        <i className={`iconfont ${item.icon}`} />
      </i>,
        label: item.title
      newMenuTarget[item.id] = menuItem
      if (item.children) {
        oldMenus.push(...item.children)
      const {parent_id} = item
      if (parent_id && newMenuTarget[parent_id]) {
        const target = newMenuTarget[parent_id as string]
        if (target?.children) {
          target.children.push(menuItem)
我该如何解决这个错误提示。
