@akashrathod28 you need to change the way how you are running the tests on GHActions here : https://github.com/Alfresco/alfresco-content-app/pull/3261/files#diff-fc79da000cf778fb8dda1c2f9847c2c4ae107459e10b85a04ee7eac531cc4082R51

It's no longer npx playwright test --config <path>, it won't work. As you can see there are still errors with lack of users data. You can check it also on your local - try to execute this npx playwright... as you do it here and you will get the same issue as here on CI. You need to modify it, to execute the Playwright tests by using nx run <project>:e2e command. This is the only way how you can do that. I advise you, to create a new action yml file, which will be only for Playwright and there do all the logic.
