Hi @anjalii-28. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

This PR fixes the panic caused by DeletedFinalStateUnknown in the ConfigMap informer and adds tests to ensure delete events are handled safely.

PTAL, thanks!

easy cla isn't satisfied - unsure if you need to sign older commits?

git rebase --signoff HEAD~N 

Generally though I thought it was tied to the email in your github account
