TypeError：无法读取未定义的属性（读取“add_cookies”）

Question

I am getting this error:

TypeError: Cannot read properties of undefined (reading 'add_cookies')

But I am unsure how I can declare it further? What amI doing wrong in the code?

Added the snippet below:

import { test, expect, browser_context, add_cookies} from '@playwright/test';

test('test', async ({ page, }) => {

  await page.goto('https://myurl.com/');
  
  await page.waitForTimeout(4000)

  browser_context.add_cookies(["cookiename", "myvalue"]

Answer 1

you can pass through a browser object that give you a context to be sure to be able to add cookie

test('test', async ({ page, browser })) => {

   await page.goto('https://myurl.com/');
  
   await page.waitForTimeout(4000)
  
   const browserContext = await browser.newContext();
   browserContext.add_cookies(["cookiename", "myvalue"];
 }
