Are event handlers necessary for RPC?

Are event handlers now necessary? I have workers I don't want to expose to fetch and only want to invoke via RPC. Why cant I do something like:

import { WorkerEntrypoint } from "cloudflare:workers";

export default class extends WorkerEntrypoint {
    async add(a: number, b: number) {
        return a + b;
    }
}

import { WorkerEntrypoint } from "cloudflare:workers";

export default class extends WorkerEntrypoint {
    async add(a: number, b: number) {
        return a + b;
    }
}

without getting this error:

 The uploaded script has no registered event handlers. Please visit the following

RR v7 framework mode subdomain getSession issue

I have 2 apps, a frontend and an API. API has auth instance and frontend has auth client. both different subdomains. I am unsure how to get getSession working in a loader function on my frontend since technically its a server side call...? useSession works but can't get getSession to work. It is working locally which is strange. Both apps deployed on cloudflare workers. Frontend app is using react router v7 framework mode and hono for SSR. This is my loader

export async function loader({ request }: LoaderFunctionArgs) {
    const { data: session } = await getSession({
        fetchOptions: {
            headers: request.headers,
        },
    });

    if (!session) {
        throw redirect("/signin");
    }
    return {
        session,
    };
}

export async function loader({ request }: LoaderFunctionArgs) {
    const { data: session } = await getSession({
        fetchOptions: {
            headers: request.headers,
        },
    });

    if (!session) {
        throw redirect("/signin");
    }
    return {
        session,
    };
}

Is it possible to use spanner nodejs client library in workers?

Anyone know if it's possible to use the nodejs spanner client library in a cloudflare worker with node compatibility flags? I tried but failed so just wanted to check if it's a skill issue. I get this error:
