I want to fix the failed e2e-test, but all e2e tests are successful in my local development environment

The Event "ingress updated" would trigger only once in the above test case, but this log collected from apisix-ingress-controller shows the Event "ingress updated" Constantly trigger. Do you know why ？

Can you try to merge master branch?
