!  We were unable to load your functions code. (see above)

This is my index.tx(root)

import * as functions from 'firebase-functions';
import React from 'react';
import { renderToString } from 'react-dom/server';
import App from './src/App';

import express from 'express';
import fs from 'fs';

const index = fs.readFileSync(__dirname + '/index.html', 'utf-8');

const app = express();
app.get('**', (req, res)=>{
    const html = renderToString(<App />);
    const finalHtml = index.replace('<div id="root"></div>', `<div id="root">${html}</div>`);
    res.set('Cache-Control', 'public, max-age=600, s-maxage=1200');
    res.send(finalHtml);
})

export let ssrapp = functions.https.onRequest(app);

This is my firebase.json

{
  "hosting": {
    "public": "dist",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "function": "ssrapp",
        "destination": "/index.html"
      }
    ]
  },
  "functions": {
    "predeploy": {},
    "source": "functions"
  }
}

NOTE: I'm using express 4.17.1, and node version 14. The host is working very well i'm only having problem with functions

EDIT: I change the ".gif" and it continues showing error, so I decided to remove it, only for debug, well, the error continues to another image(another PNG), the error appears to be in images

Answer 1

It looks like you're trying to import a *.gif image somewhere (but not in the provided code); by default, importing GIFs is not supported.

If I'm correct, then you need to setup Webpack (or its alternatives) in order to handle imports of GIF files.
