Hi
I keep getting this error when i run even a sample K6 browser script
Can you please help ?

import { browser } from ‘k6/experimental/browser’;
import { check } from ‘k6’;

export const options = {
scenarios: {
ui: {
executor: ‘shared-iterations’,
options: {
browser: {
type: ‘chromium’,
},
},
},
},
thresholds: {
checks: [“rate==1.0”]
}
}

export default async function () {
const context = browser.newContext();
const page = context.newPage();

try {
await page.goto(‘My messages’);

page.locator('input[name="login"]').type('admin');
page.locator('input[name="password"]').type('123');

const submitButton = page.locator('input[type="submit"]');

await Promise.all([page.waitForNavigation(), submitButton.click()]);

check(page, {
  'header': p => p.locator('h2').textContent() == 'Welcome, admin!',
});

} finally {
page.close();
}
}
