解决NextAuth.js FirestoreAdapter的TypeError: resolver is not a function问题

核心问题出在你的[...nextauth].js文件里NextAuth的调用方式错误——NextAuth只接受单个配置对象参数，你错误地把adapter作为第二个参数单独传入，导致API解析器无法识别，触发了resolver is not a function错误。

修正后的`[...nextauth].js`代码

import NextAuth from "next-auth";
import GoogleProvider from "next-auth/providers/google";
import LinkedInProvider from "next-auth/providers/linkedin";
import { FirestoreAdapter } from "@next-auth/firebase-adapter";

export const authOptions = {
  callbacks: {
    async redirect({ url, baseUrl }) {
      // Allows relative callback URLs
      if (url.startsWith("/")) return `${baseUrl}${url}`;
      // Allows callback URLs on the same origin
      else if (new URL(url).origin === baseUrl) return url;
      return baseUrl;
    },
  },
  // 把FirestoreAdapter放到authOptions对象内部
  adapter: FirestoreAdapter(),
  // Configure one or more authentication providers
  providers: [
    GoogleProvider({
      clientId: process.env.GOOGLE_ID,
      clientSecret: process.env.GOOGLE_SECRET,
    }),
    LinkedInProvider({
      clientId: process.env.LINKEDIN_CLIENT_ID,
      clientSecret: process.env.LINKEDIN_CLIENT_SECRET,
    }),
  ],
};

// 仅传入authOptions一个参数
export default NextAuth(authOptions);
