500 error on getKindeServerSession() in 2.3.7 (fixed in 2.5)

TL;DR: if getKindeServerSession() throws a 500 in @kinde-oss/kinde-auth-nextjs 2.3.7 for logged-out users (e.g. checking isAuthenticated in a navbar), upgrade to 2.5 or newer. The no-session case crashed in 2.3.7 and the maintainers shipped the fix in 2.5 (it was in pre-release as 2.5.0-13 first).

Steps

1. Upgrade:

npm install @kinde-oss/kinde-auth-nextjs@^2.5.0

2. Load a page with the auth-dependent UI while logged out.

   Expected: no 500. Success check: the navbar renders the logged-out state instead of crashing.

When to use this

• 500 from getKindeServerSession() with no active session; everything works after login.
• Seen on Next 15.1.4 / React 19 with kinde-auth-nextjs 2.3.7.

When NOT to use this

• Auth fails after login too; that is a different session problem.
• You are already on 2.5+ and still see it; report it as a regression.

Compatibility

• @kinde-oss/kinde-auth-nextjs 2.5+.

Variant phrasings

• "kinde getKindeServerSession 500"
• "kinde-auth-nextjs isAuthenticated navbar crash"

Root cause

The 2.3.7 code path did not handle the no-session case and threw instead of returning an unauthenticated result.

Edge cases

• Any component that reads session state on public pages (navbars, footers) hits this; audit them all after upgrading.

In the thread 500 error on getKindeServerSession() in 2.3.7 (fixed in 2.5), the question was: Calling getKindeServerSession() in @kinde-oss/kinde-auth-nextjs 2.3.7 threw a 500 error (e.g. when checking isAuthenticated in a navbar for a logged-out user). After login everything worked; the error only appeared with no active session. Seen on Next 15.1.4 / React 19. The verified resolution: Fixed in the 2.5 release of @kinde-oss/kinde-auth-nextjs; upgrade to 2.5 or newer. The maintainers confirmed the fix and it was in pre-release as 2.5.0-13 before the final. If you render auth-dependent UI like navbars, the fixed version handles the no-session case instead of throwing. Original discussion: https://vectle.com/threads/thryoUuvCc8c56CzsTXf6N5A
