[Bug]: Protocol error (Browser.grantPermissions): Unknown permission type: accessibilityEvents

[dgsayer1]

Version

1.49.0

Steps to reproduce

1. Upgraded playwright to version 1.49.0 from 1.48.2
2. Ran our set of tests (playwright test --workers=1 --project=smoke)

All tests failed with the error Error: browser.newContext: Protocol error (Browser.grantPermissions): Unknown permission type: accessibilityEvents

3. Disabled the following by commenting out the code:

   /* contextOptions: {
      permissions: ['clipboard-read', 'clipboard-write', 'accessibility-events'],
    }, */

4. Re-ran the tests

All tests passed

5. Downgraded playwright version to 1.48.2
6. Rerun tests

All tests passed

I've attached out playwright.config.ts code in the Additional Context section. Unfortunately I am unable to provide further test code.

Additionally, I've checked the Playwright readme document for granting permissions and it looks like the playwright.config.ts is correctly setup.

Expected behavior

All tests should run.

Actual behavior

All tests failed

@dgsayer1 Thank you for the issue! Indeed, this permission has been removed from Chromium by this change.

Overall, permissions are not stable and change between browsers and versions. I've updated the docs to mention this in #33690. Let me know what you think.

Perfect @dgozman, thank you for investigating and resolving so quickly.
