Uuid.v4() in loop always return the same value

App Building

I have a transformer that do something like this:

const windowList = [];
for (let i = 0; i < 10; i++) {
  const window = {
    windowId:  {{ uuid.v4(i) }}
  }
  windowList.push(window)
}

return windowList

I am expecting a list of window object with different windowId, but the result is a list of the same id. How do I run uuid.v4() in for loop and get different result for each?

Can I please get any help or suggestion on this?

Set a temp state value at beginning of loop, where windowId is use the temp state value

Something like...

const windowList = [];
for (let i = 0; i < 10; i++) {
{{ tempstate1.setValue(uuid.v4()) }}
  const window = {
    windowId:  {{ tempstate1.value }}
  }
  windowList.push(window)
}

return windowList

Thank you for stepping in, @stevenhdsdoor :pray: Love to see it. I also have another option/small observation!

Your code actually seems to work for me in a JS Code query (instead of a JS transformer). You don't need to pass in i (since I'm not sure if the uuid library supports that) and you don't need double curlies in a JS Code query.

const windowList = [];
for (let i = 0; i < 10; i++) {
 const window = {
 windowId: uuid.v4()
 }
 windowList.push(window)
}

return windowList
