Scraper works locally but not on a server

I am working on a Firebase Function website scraper to grab basic Open Graph meta tags from any website.

My function works perfectly fine when running locally as an emulator, but once I deploy my function up to the cloud and call it from my app it gets blocked by all major sites.

It seems once the scraper is run from a server it is detected as a robot, and stops working altogether. Any ideas why this may be happening?

Scraper code:

import * as functions from "firebase-functions";
import fetch, { Headers } from "node-fetch";
const cheerio = require("cheerio");

const headers = new Headers({
  "User-Agent":
    "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36",
  Accept:
    "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8",
  "Accept-Language": "en-US,en;q=0.5",
  "Accept-Encoding": "gzip, deflate",
  Connection: "keep-alive",
  "Upgrade-Insecure-Requests": "1",
  "Sec-Fetch-Dest": "document",
  "Sec-Fetch-Mode": "navigate",
  "Sec-Fetch-Site": "none",
  "Sec-Fetch-User": "?1",
  "Cache-Control": "max-age=0",
});

export const getUrlData = functions.https.onCall(
  async (data, context) => {
    try {
      const response = await fetch(data.url, { headers });
      const html = await response.text();
      const $ = cheerio.load(html);

      const title = $('meta[property = "og:title"]').attr("content") || $("title").html();
      const image = $('meta[property = "og:image"]').attr("content");

      return {
        title,
        image
      };
    } catch (e) {
      throw Error(e)
    } 
  }
);
