AWS Lambda return "Internal Server Error" - node.js

Question

My version Node.js 14.x
When using https.request return "Internal Server Error" :
const https = require('https');
exports.handler = async(event) => {
console.log(event);
let dataString = ''
const response = await new Promise((resolve, reject) => {
const { pathParameters } = event;
if (!pathParameters || !pathParameters.id) {
resolve({
statusCode: 400,
body: 'Please provide a id!'
})
}
const options = {
hostname: 'pokeapi.co',
path: `/api/v2/pokemon/${pathParameters.id}`,
port: 443,
method: 'GET',
headers: { 'Content-Type': 'application/json' }
};
const req = https.request(options, function(res) {
res.on('data', chunk => {
console.log(chunk);
dataString += chunk;
});
res.on('end', () => {
resolve({
statusCode: 200,
body: JSON.stringify(JSON.parse(dataString), null, 4)
});
});
});
req.on('error', (e) => {
reject({
statusCode: 500,
body: 'Something went wrong!'
});
});
});
return response
;};
https.get works well :
const https = require('https');
exports.handler = async(event) => {
console.log(event);
let dataString = ''
const response = await new Promise((resolve, reject) => {
const { pathParameters } = event;
if (!pathParameters || !pathParameters.id) {
resolve({
statusCode: 400,
body: 'Please provide a id!'
})
}
const req = https.get(`https://pokeapi.co/api/v2/pokemon/${pathParameters.id}`, function(res) {
res.on('data', chunk => {
console.log(chunk);
dataString += chunk;
});
res.on('end', () => {
resolve({
statusCode: 200,
body: JSON.stringify(JSON.parse(dataString), null, 4)
});
});
});
req.on('error', (e) => {
reject({
statusCode: 500,
body: 'Something went wrong!'
});
});
});
return response;
};
{pathParameters.id} this is the id that I get from the gateway and I need to handle it in a function. I must say right away that this is not because of the quotes in the path and not in the port. There are no errors in the CloudWatch logs. I am connecting lambda function to AWS gateway http.

This is not a solution, but now I see an error in the logs after listening to the answer about increasing the timeout.

I also found a workaround using
http.get(option, function (res) {.....
instead of
http.reguest(option, function (res) {.....

Answer 1

Your Lambda is timing out after the default 3 seconds:
2021-07-28T19:21:40.823Z 86503ade-fd54-400a-bd39-d58cd9d5cc45 Task timed out after 3.00 seconds
You'll need to increase this in either the AWS console (AWS Lambda -> Functions -> function_name -> General configuration -> Edit and set timeout) or via your method of deployment.
