The problem is that, for conditional types inside an Omit, TS does not resolve its value, it just says "it's looks like A['key']".
My ugly solution is to retrieve its resolved parent with objectType, and if this parent looks like type A<T> = T extends B ? C : D, then I resolve both sides of the ternary and for each I get the property value and create an union.

IMHO, it seems only partially hacky.
We have a known case that we handle conditionally, it does not produce any side effects in the Core repo and none in the X repo—sounds like a solution to me. 🤔 🙈 💡

Make sens for the generation of proptypes 👍
I assume TS only keep the index pointing to it in order to easily manage the case where the condition get defined. Which we don't care for proptypes

I don't know why TS does not work correctly with this type combination and this fix is super ugly.
But it works 😬
