Angular 19 SSR cloud functions ESM build

[chakrachi]

• unable to serve/deploy ssr functions esm build artifacts with vanilla cloud functions
• able to ng serve, ng build (build-angular:application), and node ./server.mjs
• other functions unrelated to SSR are working (server backend) as intended

Heres my SSR setup:

universal.ts

import { onRequest } from 'firebase-functions/v2/https';
import { render } from '../../render.js';
import express, { Request, Response, NextFunction } from 'express';
import * as server from '../../../dist/stamp-app/server/server.mjs';
export const ssrApp = express() as any;

ssrApp.use(express.static('dist/stamp-app/browser'));
ssrApp.get('*', async (req: Request, res: Response, next: NextFunction) => {
	const ssr: any = await render(server, req, res, next);
	res.send(ssr);
});

export const universal = onRequest(
	{ maxInstances: 10, timeoutSeconds: 1200, cpu: 1, memory: '2GiB', region: ['us-central1'] },
	ssrApp
);

render.js

import { Request, Response, NextFunction } from "express";

export async function configServerApp(app: any, req: Request, res: Response, next: NextFunction) {
  //configure app here & retrieve HTML
  let template;
  if (req.path === '/') {
    // template = await fetch('@dist/stamp-app/browser/index.csr.html');
    next();
  }
  template = `<div>HTML CONTENT FOR SSR APP</div>`;
  return template;
}
export async function render(app: any, req: Request, res: Response, next: NextFunction) {
  const ssrApp = await configServerApp(app, req, res, next);
  return ssrApp;
}

am I missing something..? thanks for any help in advance
