Cannot read properties of undefined (reading 'type')

[VictorGlindasPaf]

After updating from 1.3.1 to 1.5.2, the following code throws an exception when linting:

import { expect } from '@playwright/test';
...
 await expect 
    .poll(() => getMockHistory(received), { message })
    .toEqual(expect.objectContaining({ calls: 1, data, query: query ?? expect.anything() }));

The exception:

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

Same here. I bumped versions incrementally and 1.4.0 is the culprit release that started showing this error.

Unsure if this is related, but since upgrading any files inside a test or __test__ directory anywhere in my project are being linted by this plugin rather than just playwright tests.

@greggb Indeed unrelated, but in general when using this plugin you should scope it to only the directory containing your Playwright tests.
