Error: Clerk: auth() and currentUser() are only supported in App Router (/app directory).

Context

'Clerk: auth() and currentUser() are only supported in App Router (/app directory)' even though the code is in the app directory.

Verified resolution

Reporters found the cause is calling auth() outside a request scope: e.g. at module level in a shared /lib helper, a stale 'src' folder confusing route detection, or calling it during module init of an SSR client factory instead of inside the component/handler. Fix: call auth() inside the React component or request handler, not at module scope.
