构建时类型不可分配给类型“never”（Next.js、TypeScript）错误

Question

尝试构建我的项目时，控制台中出现此错误：

.next/types/app/facebook/page.ts:8:13
Type error: Type 'OmitWithTag<typeof import("D:/projects/abkh24/client/app/facebook/page"), "metadata" | "default" | "config" | "generateStaticParams" | "revalidate" | "dynamic" | "dynamicParams" | "fetchCache" | "preferredRegion" | "runtime" | "maxDuration" | "generateMetadata", "">' does not satisfy the constraint '{ [x: string]: never; }'.
  Property 'fetchUser' is incompatible with index signature.
    Type '(id: string, token: string) => Promise<UserData | null>' is not assignable to type 'never'.

   7 | // Check that the entry is a valid entry

error Command failed with exit code 1.

这是具有

fetchUser

功能的组件，向

Facebook Graph API

发出请求以获取某些用户的头像和其他工作人员。我尝试输入它，但出现错误。该组件的代码如下：

"use client";

import { Box } from "@mui/material";
import React, { useState, useEffect, Fragment } from "react";
import Spinner from "@/components/Spinner";
import { useIsMount } from "@/misc/tools";
import { useAppDispatch, useAppSelector } from "@/store/hooks";
import { setAuth } from "@/store/authSlice";
import { RootState } from "@/store";
import { redirect } from "next/navigation";

const ACCESS_TOKEN = process.env.NEXT_PUBLIC_ACCESS_TOKEN;

type UserData = {
  avatar: string;
  category: string;
  name: string;
};

function stringBetweenStrings(
  startStr: string,
  endStr: string,
  str: string,
): string {
  const pos = str.indexOf(startStr) + startStr.length;
  return str.substring(pos, str.indexOf(endStr, pos));
}

export const fetchUser = async (
  id: string,
  token: string,
): Promise<UserData | null> => {
  try {
    const response = await fetch(
      `https://graph.facebook.com/${id}?fields=name,picture&access_token=${token}`,
    );
    const data = await response.json();
    return {
      avatar: data.picture.data.url,
      category: "facebook",
      name: data.name,
    };
  } catch (error) {
    console.error("Error fetching user data", error);
    return null;
  }
};

export default function page() {
  const { name, avatar, category } = useAppSelector(
    (state: RootState) => state.auth,
  );
  const dispatch = useAppDispatch();
  const isMount = useIsMount();
  const [facebookId, setFacebookId] = useState<string>('');
  useEffect(() => {
    const myUrl = window.location.href;
    setFacebookId(stringBetweenStrings("id=", "#_=_", myUrl));
  }, []);

  useEffect(() => {
    (async () => {
      if (!isMount && ACCESS_TOKEN) {
        const data: UserData | null = await fetchUser(facebookId, ACCESS_TOKEN);
        dispatch(setAuth({ ...data, id: facebookId }));
      }
    })();
  }, [facebookId]);

  useEffect(() => {
    if (!isMount && category) {
      redirect("/");
    }
  }, [category]);

  return (
    <Fragment>
      <Box
        sx={{
          position: "fixed",
          zIndex: 111,
          top: 0,
          left: 0,
          height: "100vh",
          width: "100%",
          display: "flex",
          justifyContent: "center",
          alignItems: "center",
          background: "#fff",
        }}
      ></Box>
      <Spinner />
    </Fragment>
  );
}

该项目基于

Next.js 13

，使用

Eslint

等工具。谢谢关注。
