Error: Error occurred while parsing your function triggers.

undefined

Not sure what this means. it doesn’t even tell me what’s undefined.

When I take out this code though, it works. I’m trying to use angular platform server onto my app,

require('zone.js/dist/zone-node');
const express = require('express');
const path = require('path')

const renderModuleFactory = require('@angular/platform-server').renderModuleFactory;

const AppServerModuleNgFactory = require('./dist-ssr/main.bundle').AppServerModuleNgFactory;

const index = require('fs').readFileSync(path.resolve(__dirname, './dist/index.html'), 'utf8');

const app = express();

app.get('/', (req, res) => {
  renderModuleFactory(AppServerModuleNgFactory, { document: index, url: '/' })
  .then(html => {
    res.send(html);
  })
  .catch(err => {
    console.log(err)
  });
});

exports.ssr = functions.https.onRequest(app);

take me 5 hours, add:

import ‘reflect-metadata’; problem gone.

Reason: I’m not using firebase serve --only functions , instead of that, I’m running node index.js at functions folder, it give much better log, after that, I detected this error because lack of metadata. finally, I got that line.

BAD LOGGING

ACTUALLY PROBLEM
