The plugin cypress workflow is failing in the before all function for the test suites (example), suggesting a problem with the environment setup. As mentioned in the PR description, the tests are passing on a 2.17.1 security-enabled domain.

Backport needed? And do we have any plan to fix the issue that SA cypress test cases can not be run in Github CI.

Backport needed?

@SuZhou-Joe Yes, please backport this PR to 2.x, and 2.17.

And do we have any plan to fix the issue that SA cypress test cases can not be run in Github CI.

It looks like the CIs are failing in PRs to main branch for other plugins too (example). Considering the tests are failing for multiple plugins in the before all function, It seems to that there's an issue with the test environment brought up as opposed to an issue with the plugins themselves.

Does the functional test repo team have any thoughts on what could be the problem?
