Using CF Worker for LINE Webhook and get data from RestAPI

Developers Workers
1

I’m using Workers endpoint URL to set in LINE webhook. When user send ‘text’ in LINE chat it will send shipping track information back to user with Rest API of ThailandPost.

I deployed this code and test for many times until it worked. I recieved data from API but I can be used a few times It can’t anymore.

Important In my CF account I have a same code in full projects but it can recieved data about 8 in 10 (cancelled status sometime) but other projects with same code it not work.

I try to use all code and create new workers it not work the same. So that made me very confused about the problem.

Example code below I just want to get the data from API to show in CF Logs first.

//index.js
const { getItems } = require('./thailandpost.js');

export default {
    async fetch(request, env) {
        const bodyText = await request.text();
        console.log(bodyText)
        const bodyJSON = JSON.parse(bodyText);
        const event = bodyJSON.events[0];

        if (event.type === "message" && event.message.type === "text") {
            const barCode = event.message.text;
            console.log(barCode)
            const trackResult = await getItems(barCode);
            console.log(trackResult);
            return new Response({ status: 200 });
        }
        return new Response('Hello Cloudflare Worker!');
    }
}

//thailandpost.js
const THAILAND_POST_GETTOKEN = 'https://trackapi.thailandpost.co.th/post/api/v1/authenticate/token'
const THAILAND_POST_GETITEMS = 'https://trackapi.thailandpost.co.th/post/api/v1/track'
const ACCESS_TOKEN = 'MYTOKEN'

	async function getToken() {
		const headers = {
			Authorization: `Token ${ACCESS_TOKEN}`,
			"Content-Type": "application/json"
		}
		const options = {
			method: "POST",
			headers
		}
		const response = await fetch(THAILAND_POST_GETTOKEN, options)
		const result = await response.json()
		return result
	}

	async function getItems(barCode) {
		const authToken = await getToken()
		const data = {
			status: "all",
			language: "TH",
			barcode: [barCode]
		}
		const headers = {
			Authorization: `Token ${authToken.token}`,
			"Content-Type": "application/json"
		}
		const options = {
			method: "POST",
			headers,
			body: JSON.stringify(data)
		}
		const response = await fetch(THAILAND_POST_GETITEMS, options)
		const result = await response.json()
		return result
	}

module.exports = { getItems };

I’m trying to recheck API key and others in test.js with command node src/test.js
It completed and received data in terminal 100% work
but in CF workers still can’t.

//test.js
const { getItems } = require('./thailandpost.js');

async function testThailandPostAPI() {
        const barCode = "EM352846050TH";
        const trackResult = await getItems(barCode);
        console.log('Track Result:', (trackResult));
}
testThailandPostAPI();

//Terminal
PS C:\Users\AAAAA\Desktop\post-tracking> node src/test.js
Track Result: {
  response: {
    items: { EM35XXXX050TH: [Array] },
    track_count: {
      track_date: '28/03/2567',
      count_number: 1,
      track_count_limit: 1000
    }
  },
  message: 'successful',
  status: true
}
