Ignore DiscardResponseBodies in setup

Thanks for the awesome tools.

Currently I am setting the options of k6 to discard response bodies

export const options = {
  discardResponseBodies: true

This will discard all the bodies of the http response in setup and vu step I assumed.

So how could I fetch the JSON response in setup step to use in vu step meanwhile still discard the response bodies in vu step?

I already tried with setting Params.responseType to text but it seems the discardResponseBodies will overwrite set the body to null with this option.

Thanks in advance,

This is the way to negate discardResponseBodies and get the response body of individual requests. Can you share a code snippet that demonstrates the issue, since I can’t reproduce it. This code works like how you’d expect it to work:

import http from 'k6/http'

export let options = {
    discardResponseBodies: true,

export function setup() {
    let res1 = http.get('https://test.k6.io/');
    console.log(res1.body); // prints null
    let res2 = http.get('https://test.k6.io/pi.php?decimals=3', { responseType: "text" });
    console.log(res2.body); // prints the body

export default function () {

Thanks for taking a look into the issue.

I retried the same code structure and the feature worked flawlessly. What I did was power off the computer and went home :smile: Probably I made a mistake when using responseType. Silly me!

If any issue arises in this category, I will let you know.

Thank you for taking your time. Please consider this issue resolved.
