WhatsApp 消息的 Lambda AWS 和 Twilio 出现“X 秒后任务超时”错误

Question

I was trying to implement a Lambda function to Send WhatsApp messages with Twilio service.

I have already uploaded the twilio npm package (I was getting the "cannot fin twilio module", but I added the layer and I don't get the error anymore). I'm using node 14 and my zipped npm package is with the nodejs/node_modules... structure (not the node14, but I understood it can work with both). Maybe this is why it's not working?

I got stuck after that. I keep getting the "taks timed out". I changed from the default 3 to 5 seconds, but it still gets errors.

What am I missing or doing wrong? This is my code:

'use strict';
console.log('Trying to send a WhatsApp message...');

exports.handler = async (event) => {
    
const accountSid = 'ACa4818d82a4d6----------'; //The hyphens is to hide credentials or phone numbers
const authToken = '7e5d8205968af11----------'; 

const client = require('twilio')("ACa4818d------", "7e5d8205968af11-------");
//I event passed the parameters like this to troubleshoot
 
client.messages 
      .create({ 
         body: 'Hi, there!', 
         from: 'whatsapp:+14------',       
         to: 'whatsapp:+1-------' 
       }) 
      .then(message => console.log(message.sid))
      .done();
};

This is the response in Lambda console:

Test Event Name

}

Answer 1

I solved this by increasing the timeout time.

I changed from 5 seconds to 1 minute. Looks like the first request in a while takes around 15 seconds. Request afters that take miliseconds.

Answer 2

The same error also happens, do you know why the first request takes so long?

let response = await this.instance.post("/messages", parameters, {
            headers: {
                Authorization: `Bearer ${tokenDev}`,
            },
        });

In my case I use the WhatsApp API directly. In local it works fine for me but when uploading it to a lambda the error occurs.
