How to get a session in NextJS Middleware

I have an application that was set up using NextJS 15.3.1 and the 4.0.0-beta.0 nextjs-auth0 SDK. I can see that this SDK has been brought into a stable version and am attempting to update to use it but am running into an issue.

How can I access a session object from my middleware? My original middleware setup was something like…

export async function middleware(request: NextRequest) {
    const businessUnit = detectBusinessUnitFromRequest(request);
    const auth0 = await createAuth0Client(businessUnit);
    const authResponse = await auth0.middleware(request);

    if (request.nextUrl.pathname.startsWith('/auth')) {
        return authResponse;
    }

    const session = await auth0.getSession();

    // assorted route access checks based on user permissions from the session object

    return authResponse;
}

export const config = {
    matcher: ["/((?!_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)"],
}

That await auth0.getSession() now throws a NextJS error for calling cookies outside of a request scope. What is the alternative? How else can I access the users data and access tokens here in the middleware?
