将 next-auth 应用程序部署到 Vercel 会在凭据提供程序中创建错误

Question

我正在尝试将我的下一个应用程序部署到 Vercel。我正在使用 next-auth 通过凭据和 api returns JWT 进行身份验证。在本地主机上它工作正常，但是当我把它放在 Vercel 上并尝试登录时，没有任何反应。但是，当我在项目的仪表板功能中查看日志时，出现错误：

Runtime.ExitError

补充信息： SignIn() 函数如下所示：

signIn("credentials", {
        email: values.name,
        password: values.password,
        redirect: false,
        callbackUrl: `/app`
      })
        .then((data) => console.log("loginpagethen", data))
        .catch((error) => console.log("loginpagecatch", error));

我认为问题出现在 jwt callback 函数的某处，因为 authorize returns 一个用户（具有所有数据，包括来自服务器的 jwt）。另外，如果我在 jwt callback 函数中 console.log 用户，我实际上可以看到用户对象。但是会话不存在。

 async jwt({ token, user, account, profile, isNewUser }) {
    if (user) {
      console.log("user", user); //user is there
      token.accessToken = user.token;
    }
    return token;
  },

  async session(session, token) {
    console.log("session", session); //session is not there
    return session;
  },
};

P.S。我添加了环境变量。

关于如何让我的应用程序在 vercel 上运行有什么想法吗？

Answer 1

在您的 .env 文件中创建一个环境变量：

API_SECRET_KEY=q3t6w9z$C&F)asdfasdfasfasdfasdfasd1sdfasf

Deploying next-auth app to Vercel creates error in credentials provider

next.js
