Understanding and Fixing 'locator.fill: Target closed' Error in Playwright

When you see the 'locator.fill: Target closed' error in Playwright, it means that the target element you're trying to fill with data has been closed or destroyed before the fill action could be completed. This could be due to a page redirect or refresh during test execution.

How to Fix

To fix this, you need to ensure that the target element remains open and available for filling throughout your test. Here's how:

Use Wait Methods

In your test script, use wait methods to ensure that elements are fully loaded and ready before you perform any actions on them. Here's an example:

import { test } from '@playwright/test';

test('wait for element', async ({ page }) => {
  await page.goto('https://ray.run/');
  const locator = page.locator('#targetElement');
  await locator.waitFor();
  await locator.fill('Some data');
});

Use Specific Locators

Another way is to use more specific locators when identifying elements in your tests. Using unique identifiers such as IDs or data attributes can reduce the likelihood of accidentally targeting an incorrect element or one that may be destroyed during test execution.

import { test } from '@playwright/test';

test('use specific locator', async ({ page }) => {
  await page.goto('https://ray.run/');
  const locator = page.locator('#uniqueId');
  await locator.fill('Some data');
});
