Combining JSON into a single structure

Describe the problem/error/question

I’m trying to implement this function to combine 5 JSON structures… sorry bit of a noob with JavaScript. Am i doing something wrong?

function combineIntoLookAlikeDomains(json1, json2, json3, json4, json5) {
return {
look_alike_domains: {

const json1 = $(‘MAIN’).first().json;
const json2 = $(‘CVE’).first().json;
const json3 = $(‘CERTIFICATE’).first().json;
const json4 = $(‘IPADDRESS’).first().json;
const json5 = $(‘HOST2’).first().json;

const combinedJson = combineIntoLookAlikeDomains(json1, json2, json3, json4, json5);

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Hi @alykhan, welcome to the community!

Looks like all that’s missing is a final return statement. Try adding return combinedJson; below your existing code :slight_smile:

In a workflow this looks like so:

Result (this is of course random dummy data, just to illustrate the idea):

Hope this helps!


Perfect thank you so much!
