Hi @MattDelac. Thanks for your PR.

I'm waiting for a feast-dev 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/test-infra repository.

Rerunning the tests now. Codecov has a bug that I tried to fix. You may need to rebase on master. 3b22005

That did not help for now

[woop]

I think we have to wait for it to be resolved here: codecov/codecov-action#330

For the time being I will turn off failure in CI
