cant really help much with ur question without u providing additional context, or code snippets

But it COULD be cuz u don't have a "use server" at the top of ur auth.ts file

[minor drift]

Authentication libraries store the user token in the cookies, when you “signOut()” you’re effectively deleting the cookie via “cookies.delete()” which is an operation that can only happen in Server Actions or Route Handlers, that’s because these two have access to the requests headers.

Request Headers allow you to operate with cookies via the “HTTP Cookie” header, sending or modifying information on the client side (cookies are only stored on the client side)

Idk if I understood your question correctly, a little more context would help

In your case, I would create a folder with actions for auth: actions/auth

“use server”;

export async function signIn(){ … }

export async function signOut(){
….
signOut()
// or whatever way your
// auth library handles this
…
}
