[Bug] TypeScript error: Module '"next-auth"' has no exported member 'NextAuthConfig' in auth.config.ts #455

Description

Problem

In auth.config.ts (line 3), there is a TypeScript error
documented in tsc_errors.txt:

auth.config.ts(3,15): error TS2305: Module '"next-auth"'
has no exported member 'NextAuthConfig'.

The import is trying to use NextAuthConfig from
next-auth but this type is not exported by the installed
version of the package, causing a TypeScript compilation
error.

Impact

  • TypeScript build fails with this error
  • The error is already tracked in tsc_errors.txt
    confirming it is a known unresolved issue
  • Affects auth configuration reliability

Proposed Fix

Replace the incorrect import with the correct type.
Depending on the next-auth version:

For next-auth v5 (Auth.js):
import type { NextAuthConfig } from "next-auth"
should be replaced with the correct exported type from
the installed version.

File

auth.config.ts — line 3

I'd like to work on this fix if approved!
