Request to Gemini API won't go in skaffold container

Question

I am trying to send a request to Google's Gemini API in an express server that is containerized.

import { GoogleGenerativeAI } from "@google/generative-ai";

const genAI = new GoogleGenerativeAI(process.env.GEMINI_API_KEY!);

async function run() {
  const model = genAI.getGenerativeModel({ model: "gemini-pro" });

  const prompt = "Write a story about a magic backpack.";

  const result = await model.generateContent(prompt);
  const response = await result.response;
  const text = response.text();
  console.log(text);
}

export default run;

Whenever I call this function in index.ts after calling app.listen() it throws an error saying fetch failed which looks something like this

TypeError: fetch failed
[tests]     at Object.fetch (node:internal/deps/undici/undici:11731:11)
[tests]     at processTicksAndRejections (node:internal/process/task_queues:95:5)

[tests] [ERROR] 07:42:56 Error: [GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1/models/gemini-pro:generateContent: fetch failed

I tried doing the same in a new application which is not containerized and it worked (both javascript and typescript). What is happening here and how can I fix it?
