AutoComplete照着官方的例子，为什么VSCODE会报错？

version: 2.4.4

const query = async (queryString: string, cb: (arg: any) => void) => {
  if (!queryString) {
    cb([])
  }
  const res = await getEntities(props.url, {
    filter: {
      logic: FilterLogic.OR,
      filters: props.treeProps.search.map((s: any) => ({
        type: SEATypes.String,
        operator: Operators.CONTAINS,
        field: s,
        value: queryString,
      })),
    },
  })
  cb(res.data)
}

typeScript类型校验不通过，应该是参数类型没对上，可以尝试着将 cb: (arg: any) => void 类型定义为AutocompleteFetchSuggestionsCallback

import { AutocompleteFetchSuggestionsCallback } from 'element-plus';
const query = async (queryString: string, cb:AutocompleteFetchSuggestionsCallback) => {
  if (!queryString) {
    cb([])
  }
  const res = await getEntities(props.url, {
    filter: {
      logic: FilterLogic.OR,
      filters: props.treeProps.search.map((s: any) => ({
        type: SEATypes.String,
        operator: Operators.CONTAINS,
        field: s,
        value: queryString,
      })),
    },
  })
  cb(res.data)
}

按你说的改了， 新的报错：
不能将类型“(queryString: string, cb: AutocompleteFetchSuggestionsCallback) => Promise”分配给类型“AutocompleteFetchSuggestions | undefined”。ts(2322)

[WestFarmer]

关键在于， 异步函数的返回值是 Promise<void> 而期望值是 Awaitable<AutocompleteData> | void
这文档真的是一坨屎，如果返回的是void, 是内置的callback函数将后选项添加弹出框里面的， 如果返回值是Awaitable<AutocompleteData>，则不需要调用callback函数

哈哈哈哈感觉他们没怎么维护文档，将代码更新之后，没有更新文档

[WestFarmer]

const query = async (queryString: string, cb: AutocompleteFetchSuggestionsCallback): Promise<AutocompleteData> => {
  if (!queryString) {
    //cb([])
    return []
  }
  const res = await getEntities(props.url, {
    filter: {
      logic: FilterLogic.OR,
      filters: props.treeProps.search.map((s: any) => ({
        type: SEATypes.String,
        operator: Operators.CONTAINS,
        field: s,
        value: queryString,
      })),
    },
  })
  //cb(res.data!)
  return res.data!
}
