Make a HTTP Post call within Azure Functions using Nodejs - node.js

Question

I am trying to make a HTTP Post call from within Azure Functions using nodejs. The payload which needs to be passed is in JSON with two properties title and description. For some reason, the below code doesn't work and I don't get any errors in the log too. The POST operation works in a Postman rest client. Can someone point me in the right direction? Thanks
var http = require('https');
module.exports = function (context, req) {
var body = {
"title": "Sunday",
"description": "Last day of the week"
}
const options = {
hostname: 'capservice-xxxxxxxx.ondemand.com',
port: 443,
path: '/incident/SafetyIncidents',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': body.length
}
}
var response = '';
const request = http.request(options, (res) => {
context.log(`statusCode: ${res.statusCode}`)
res.on('data', (d) => {
response += d;
})
res.on('end', (d) => {
context.res = {
body: response
}
context.done();
})
})
request.on('error', (error) => {
context.log.error(error)
context.done();
})
request.write(body);
request.end();
};

Had a bit more chance to investigate the issue. I've actually tested it on Azure Functions now - and got it to work.
Your body variable is incorrectly typed:
// This assumes that the body type is JSON.
var body = {
"title": "Sunday",
"description": "Last day of the week"
}
See the reference here: https://nodejs.dev/learn/make-an-http-post-request-using-nodejs
const https = require('https')
// See the JSON.stringify
const data = JSON.stringify({
todo: 'Buy the milk'
})
When I try to execute your function above as it is (with changing the URL) - I'm receiving a parameter error as below
FailureException: TypeError [ERR_INVALID_ARG_TYPE]: The first argument
must be of type string or an instance of Buffer. Received an instance
of ObjectStack
Adding the JSON.stringify to the body object solved the problem for me.
