鸿蒙开发报错Argument of type '(item: ObjectData) => number' is not xxxx

Argument of type '(item: ObjectData) => number' is not assignable to parameter of type '(item: any, index: number) => string'.
Type 'number' is not assignable to type 'string'. <ArkTSCheck>

报错代码

@Link lists:Array<ObjectData>;
ForEach(this.lists, (item: ObjectData) => {
  this.taskItem(item)()
}, (item: ObjectData) => item.id)

修改代码

ForEach(this.lists,(item: ObjectData) => {
  this.taskItem(item)
}, (item: ObjectData) => item.id.toString())

📌 总结一下：

错误原因	解决方式
item.id 是 number，但 ForEach 要求 string	加 .toString() 转成字符串
