I am getting this Error when running K6 Browser locally any help?
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=
These is my options:
export const options = {
scenarios: {
browser: {
executor: 'constant-vus',
vus: 10,
duration: '5m',
options: {
browser: {
type: 'chromium',
},
},
}
}
};
Hi @chingher90, welcome to the community forum!
Can you share the sanitized version of the test script also with us?
Here is the sanitized version
import { browser } from 'k6/experimental/browser';
import { sleep, check } from 'k6';
import { SharedArray } from "k6/data";
import papaparse from "https://jslib.k6.io/papaparse/5.1.1/index.js";
export const options = {
scenarios: {
browser: {
executor: 'constant-vus',
vus: 10,
duration: '5m',
options: {
browser: {
type: 'chromium',
},
},
}
}
};
// not using SharedArray here will mean that the code in the function call (that is what loads and
// parses the csv) will be executed per each VU which also means that there will be a complete copy
// per each VU
const csvData = new SharedArray("UserData", function () {
// Load CSV file and parse it using Papa Parse
return papaparse.parse(open("./data/randomData.csv"), { header: true }).data;
});
// Pick a random userID test data pair
const getCSVRandomData = csvData[Math.floor(Math.random() * csvData.length)];
console.log("Selected UserName Data: ", JSON.stringify(getCSVRandomData));
export default async function () {
const page = browser.newPage();
try {
await page.goto('https://FAKE_URL.com/index.html');
page.locator('input[name="username"]').type(getCSVRandomData.users);
page.locator('input[name="password"]').type(getCSVRandomData.password);
const submitButton = page.locator("LOGINBUTTON_XPATH");
await Promise.all([page.waitForNavigation(), submitButton.click()]);
sleep(1.0)
//Navigate to another page after login
page.goto ('https://FAKE_URL.com');
sleep(1.0)
const text = page.locator('XPATH');
if (text.isVisible()) {
console.log("element is visible");
}
} finally {
const signoutButton = page.locator('SIGNOUT_XPATH');
if (signoutButton.isVisible()) {
await Promise.all([page.waitForNavigation(), signoutButton.click()]);
console.log(" Test Successfully Sign out");
}else{
console.log("SignOut failed to locate");
};
page.close();
}
}
I confirm the script will work if I just config for only one VU for one iteration but if I bump up the VUs like the above settings …it will crash.
I have the same error, also hapenning only when I use maultiple VUs. Here is my scenario:
{
executor: 'constant-vus',
vus: 10,
duration: `4.5m`,
gracefulStop: '30s',
options: {
browser: {
type: 'chromium',
},
}
}

Hi @armaaar , welcome to the community forum!
I think your error is definitely not the same, because your error happens in the page.Screenshot function, and the previous script doesn’t even call screenshot. I assume your script calls screenshot(). Can you share the script and the html page with us?
Thanks.
You are absolutely correct! I didn’t notice the screenshot part. I’ve removed it and I’m running the tests again. Hopefully they would be fixed now.
Here is a sanetized version of the script I was running when I got the error:
export function setup() {
return getAccessToken()
}
export default async function (accessToken) {
const tags = exec.vu.metrics.tags
const browserContext = browser.newContext()
browserContext.addCookies([{ name: 'access_token', value: accessToken, tags.url }])
const page = browserContext.newPage()
try {
// Send request to server
const response = await page.goto(tags.url)
// Wait for page to load
await page.waitForNavigation({waitUntil: 'load'})
// Wait for all loaders to disappear
page.waitForSelector('.loader', {state: 'detached', strict: false})
} finally {
check(page, { 'No Loaders': p => p.isHidden('.loader', {strict: false}) })
page.screenshot({ path: `./screenshots/${tags.page}.png`, fullPage: true});
page.close()
browserContext.close()
}
}
