@zkayyali812 the coverage report said there are two missings. Could you improve it?

[zkayyali812]

Hey @hsong-rh ,
I tried to cover these lines for a bit, but haven't been able to figure out a way to sufficiently cover them in our unit testing, but I am able to confirm they work as expected in running deployments.

I was thinking that this may be sufficient for now, and ideally cover them them in our test-suite, once ATF is updated to consume this API. however if you know how I can cover these better, I would love to learn.

[zkayyali812]

@hsong-rh / @Alex-Izquierdo I think I addressed the code coverage here. Not sure if I can retrigger the codecov automation to update its comment above.
