Running k6 script for load tests returns an error - redirect

Question

I'm first time user of k6 and I've already manage to get an error when running the script:
"Request Failed [33merror[0m="Get https:///: stopped
after 0 redirects"
Script k6.js:
import http from "k6/http";
import { sleep } from "k6";
export let options = {
stages: [
{ duration: "30s", target: 20 },
{ duration: "1m30s", target: 10 },
{ duration: "20s", target: 0 },
]
};
export default function() {
let res = http.get("https://<our_page_URL>/");
check(res, {
"status code MUST be 200": (res) => res.status == 200,
}) || fail("status code was *not* 200");
sleep(1);
}
Why do I get this error and what is the solution?

You have to set up the maxRedirects option; maxRedirects is the maximum number of HTTP redirects that k6 will follow before giving up on a request and erroring out with ("Get $PATH stopped after $MAX_REDIRECT_VALUE redirects")
You can pass the option as CLI argument or script options. More about this option at https://docs.k6.io/docs/options
export let options = {
// Max redirects to follow (default is 10)
maxRedirects: 10
};
The default is 10, so there is likely a bug skipping the default value being assigned.
This is a redirect example to test how it works.
import http from "k6/http";
import {check} from "k6";
export let options = {
// Max redirects to follow (default is 10)
maxRedirects: 5
};
export default function() {
// If redirecting more than options.maxRedirects times, the last response will be returned
let res = http.get("https://httpbin.org/redirect/6");
check(res, {
"is status 302": (r) => r.status === 302
});
// The number of redirects to follow can be controlled on a per-request level as well
res = http.get("https://httpbin.org/redirect/1", {redirects: 1});
console.log(res.status);
check(res, {
"is status 200": (r) => r.status === 200,
"url is correct": (r) => r.url === "https://httpbin.org/get"
});
}
