Amadeus Hotel Search API (Self-Service APIs) with GCP Cloud Functions

Question

I'm using Amadeus Hotel Search API which is one of the their Self Service APIs for my React.js app. With deployment of Cloud Functions in GCP, there is a problem.

1. Test deployment: this is working well.

const {onRequest} = require("firebase-functions/v2/https");
const {logger} = require("firebase-functions");

exports.helloWorld = onRequest({maxInstances: 10}, (request, response) => {
  logger.info("Hello logs!", {structuredData: true});
  response.send("Hello World!!");
});

However, second one is not working.

2. Deployment of function with Amadeus Hotel Search API

const {onRequest} = require("firebase-functions/v2/https");
const Amadeus = require("amadeus");

const amadeus = new Amadeus({
  clientId: process.env.AMADEUS_CLIENT_ID,
  clientSecret: process.env.AMADEUS_CLIENT_SECRET,
});

exports.hotelOffersSearch = onRequest({maxInstances: 10}, async (req, res) => {
  try {
    const response = await amadeus.shopping.hotelOffersSearch.get({
      hotelIds: "RTPAR001",
      adults: "2",
    });
    console.log(response.data);
    res.status(200).send(response.data);
  } catch (error) {
    console.error(error);
    res.status(500).send(error.message);
  }
});

Below is a part of error message when i tried to deploy second one in command.

functions: creating Node.js 18 (2nd Gen) function hotelOffersSearch(us-central1)... Could not create or update Cloud Run service hotelofferssearch, Container Healthcheck failed. Revision 'hotelofferssearch-00001-tox' is not ready and cannot serve traffic.
The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable. Logs for this revision might contain more information.

And, If I try a request on command, it's working well like this.

What's wrong with me? I think, it's about Amadeus api issue because first test version was deployed successfully.

I'm a beginner, so please explain it in an easy way to understand.
