I'm trying to do a HTTP PUT via node js in AWS lambda, but I keep getting time outs. According to this "A Lambda function with VPC access will not have internet access unless you add a NAT", but in my case I'm not using a VPC.
exports.handler = (event, context) => {
const options = {
host: 'xxx',
path: 'xxx',
port: 443,
method: 'PUT'
};
req = http.request(options, (res) => {
console.log(res);
});
};
The problem is with Lambda node.js.
If you'd like to use node.js version 8, you should write code like this example
exports.handler = async (event, context) => {
const options = {
host: 'xxx',
path: 'xxx',
port: 443,
method: 'PUT'
};
const response = await http.request(options);
console.log(response);
};
If you don't want to use node.js version 8, you should add third parameter callback and call it after function execution.
exports.handler = (event, context, callback) => {
const options = {
host: 'xxx',
path: 'xxx',
port: 443,
method: 'PUT'
};
req = http.request(options, (res) => {
console.log(res);
callback();
});
};
The way your code is written, it is not returning anything as a response.
You can do it this way (using callback in node 4, 6 or 8) ...
exports.handler = (event, context, callback) => {
const options = {
host: 'xxx',
path: 'xxx',
port: 443,
method: 'PUT'
};
return http.request(options, (result) => {
console.log(result);
// Calling callback sends "result" to API Gateway.
return callback(null, result);
});
};
Or, if you want to use node 8's support for promises...
// You can use `async` if you use `await` inside the function.
// Otherwise, `async` is not needed. Just return the promise.
exports.handler = (event, context) => {
const options = {
host: 'xxx',
path: 'xxx',
port: 443,
method: 'PUT'
};
return new Promise((resolve, reject) => {
return http.request(options, result => {
return resolve(result)
})
})
};
You need to call req.end() after the request.
const req = http.request(options)
req.end()
