@Khadreal @jeawhanlee cc @Miraeld, for me @lcpll tests on PR #144 still fail, with error in debug.log

PHP Fatal error:  Uncaught Error: Call to undefined function undefined() in /var/www/html/hanna.e2e.rocketlabsqa.ovh/wp-content/rocket-test-data/templates/triggerErrorInDebug.php:6
Stack trace:

#3 {main}
  thrown in /var/www/html/hanna.e2e.rocketlabsqa.ovh/wp-content/rocket-test-data/templates/triggerErrorInDebug.php on line 6

And the e2e rocket helper plugin I think needs to be updated with new hook name:
PHP Deprecated: Hook rocket_lcp_delay is deprecated since version 3.16.4! Use rocket_performance_hints_optimization_delay instead. in /var/www/html/hanna.e2e.rocketlabsqa.ovh/wp-includes/functions.php on line 6078
and even though scenarios with Imagify are expected to fail due to Imagify issue, the 1 scenario at least should be expected to pass, but it fails. Sharing my results below, if one of you can help me debug. Thanks.
