Describe the issue

When trying to get user or isAuthenticated from getKindeServerSession() in client code I'm getting a 500 error on /api/auth/setup. There is nothing in the logs, even after setting the debug env variable. Downgrading to 2.3.6 fixes it. The 500 error means that I'm not able to see if a user is even authenticated from the browser.

This client example here will trigger the issue: https://docs.kinde.com/developer-tools/sdks/backend/nextjs-sdk/#protect-routes-with-kinde-auth-data

Looking into this

[peterphanouvong]

Thanks so much team, sorry about that bug! It should be fixed as a part of 2.3.8 #205

The bug is still there, and I'm using v2.3.8 with nexts14. When it comes to desktop browsers, it's a bit acceptable, but as for mobile browsers like Chrome on iPhone, it will cause a breakdown of the page.

Same issue here. I tried several versions. Now i went down to version 2.3.6. It works but i get the "401 Unauthorized" with loggedOut users which i guess was intended in this version.

Same issue as @QingjiaTsang here. Any solution?
with these dependencies
"dependencies": {
"@kinde-oss/kinde-auth-nextjs": "^2.4.3",
"next": "14.2.16",
"next-themes": "^0.3.0",
"react": "18.3.1",
"react-dom": "18.3.1",
},

[DanielRivers]

Am I right that this only occurs when there is no active session?

[Ricardosgeral]

@DanielRivers well i'm using it on the client

"use client";

import { cn } from "@/lib/utils";
import { useSelectedLayoutSegment } from "next/navigation";
import { useKindeBrowserClient } from "@kinde-oss/kinde-auth-nextjs";
import {
  RegisterLink,
  LoginLink,
} from "@kinde-oss/kinde-auth-nextjs/components";

interface NavProps {
  items?: {
    title: string;
    href: string;
    disabled?: boolean;
    external?: boolean;
  }[];
}

function SignInSignUpButtons() {
  return (
    <>
      <LoginLink
        postLoginRedirectURL="/dashboard"
        className={buttonVariants({ variant: "secondary" })}
      >
        Sign In
      </LoginLink>

      <RegisterLink
        postLoginRedirectURL="/dashboard"
        className={buttonVariants({ variant: "default" })}
      >
        Sign Up
      </RegisterLink>
    </>
  );
}

function AuthButtonsInner() {
  const { isAuthenticated } = useKindeBrowserClient();

  if (isAuthenticated) {
    return (
      <Link
        href="/dashboard"
        className={buttonVariants({ variant: "default" })}
      >
        Dashboard
      </Link>
    );
  } else {
    return <SignInSignUpButtons />;
  }
}

function AuthButtons() {
  return (
    <React.Suspense fallback={<SignInSignUpButtons />}>
      <AuthButtonsInner />
    </React.Suspense>
  );
}

Hi,
any updates on this ?

[soiloui]

I have the same problem, any news?

[rip32700]

same problems..

[walhalla-software-dev]

The problem still appears using the vanilla setup for nextjs in a fresh unmodified project... https://docs.kinde.com/developer-tools/sdks/backend/nextjs-sdk/

kinde setup: Email and Code

Environment: localhost:3000

Error:
✓ Compiled /api/auth/[kindeAuth] in 362ms (1121 modules) GET /api/auth/setup 500 in 565ms

dependencies:
"@kinde-oss/kinde-auth-nextjs": "^2.4.6", "next": "15.1.3", "react": "^19.0.0", "react-dom": "^19.0.0",

Any solutions or any working recommended setups to use kinde without errors from start?

@DanielRivers Yes, it happens only when there is no active session yet.

[kennethhaspeel]

Next 15.1.4
React 19

I'm using the isAuthenticated in a navbar to determine which menu items i want to show. If there is no logged in user i get the error mentioned above. After logging in, everything works fine. No previous login or after logout, the error pops up

I found this post in the Kinde community: https://community.kinde.com/nextjs-app-router-500-error-constant-setup-lJ0t6n4blKfx
It says to upgrade to a prelease (version 2.5.0-11).

But the error keeps on coming
