Github node action http errors always fails job - github-actions

Question

I have a github action that looks something like this:
const http = require('http');
const core = require('#actions/core');
const options = {
hostname: 'mydomain.com',
port: 80,
path: '/webhook',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
}
};
const postData = {
foo: 'bar'
}
try {
const strPostData = querystring.stringify(postData);
options.headers['Content-Length'] = Buffer.byteLength(strPostData);
const req = http.request(options)
req.write(strPostData)
req.end()
} catch (error) {
core.info(error.message);
}
if mydomain.com/webhook is offline, my job fails on this action, logging:
events.js:187
throw er; // Unhandled 'error' event
^
Error: connect ECONNREFUSED xxx.xxx.xxx.xxx:80
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1129:14)

errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',

***
Why does it fail, why doesn't the try catch catch this?
I don't want the entire job to fail if this action fails, so how do I trap this failure and hide it from the GitHub runner?

Answer 1

You will need to listen to the 'error' event to catch this
const strPostData = querystring.stringify(postData);
options.headers['Content-Length'] = Buffer.byteLength(strPostData);
const req = http.request(options)
req.on('error', (err) => {/*Error Caught*/})
req.write(strPostData)
req.end()
