可以的话，尽可能提供截图或视频来补充描述你的问题...

如何复现（请务必完整填写下面内容）：

1. 你是如何使用 amis 的？
   sdk
2. amis 版本是什么？请先在最新 beta 版本测试问题是否存在
   2.6.0
3. 粘贴有问题的完整 amis schema 代码：

{
  "type": "page",
  "body": {
    "type": "mapping",
    "value": "sad",
    "source": "${ls:aaa}"
  }
}

localstorage
aaa  =
[
      {
        "value": "happy",
        "label": "开心",
        "color": "red"
      },
      {
        "value": "sad",
        "label": "悲伤",
        "color": "blue"
      },
      {
        "value": "*",
        "label": "其他",
        "color": "gray"
      }
    ]

1. 操作步骤
   配置schema后，console会报错误信息
