Hi @EWK20. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

@EWK20 thanks for this PR. Would you please update tests accordingly ?

[EWK20]

Hi @mloiseleur, can you please highlight how i should update the tests? I had a look through the test file and saw that there are no tests that check the error returned. Thank you
