Description (Bug 描述)
Steps to reproduce (复现步骤)
表格中添加bulk edit -> Form-> 添加关系字段
Expected behavior (预期行为)
正常使用
Actual behavior (实际行为)
报错，cant not read properties of undefined (read mode)
Related issues (相关 issue)
Reason (原因)
schema的‘x-compoent-props'不一定有mode属性
Solution (解决方案)
schema['x-component-props'].?mode==='Nester'
使用可选链操作符（Optional Chaining Operator）?.。这样，如果 mode 存在，表达式将返回 mode 的值；如果 mode 不存在，则整个表达式的结果为 undefined。
