title: Node module doesn't work in Firebase hosting?
body: <p>I have a Node server and use Firebase hosting. The server uses the Node module <strong>rss-to-json</strong> for parsing a RSS feed to JSON.</p>
  
  <p>When I test the server on my machine, the request works, but when deploying it doesn't work. It just loads forever and gives:</p>
  
  <blockquote>
    <p>"Error 503 first byte timeout"</p>
  </blockquote>
  
  <p><strong>My code:</strong></p>
  
  <pre><code>const functions = require("firebase-functions");
  const express = require("express");
  const Feed = require("rss-to-json");
  
  app.get("/feed", (req, res) =&gt; {
      Feed.load("https://www.reddit.com/.rss", function(err, rss) {
          res.send(rss);
      });
  });
  
  exports.app = functions.https.onRequest(app);
  </code></pre>
  
  <p><strong>Have tried:</strong></p>
  
  <p>Removed "node_modules" from "ignore" in firebase.json, but no luck.</p>
  
  <p>Any ideas?</p>
