Hello, it seems that I actually forgot to unwrap errors from a promise…
for instance if you replace
type getThrowableType<T> = T extends throwable<infer T> ? T : never;
with
type getThrowableType<T> = T extends PromiseLike<throwable<infer T>> ? T : never;
it will work in this special case, I however need to think about a clean way to achieve this even for recursive promises (promise of promises)
we should be able to unwrap promises using Awaited
which is built in ts 4.5
from ts-throwable.
Okay, here is how to unwrap the promises:
type exceptionsOf<T extends basicFunction> = getThrowableType<Awaited<ReturnType<T>>>;
And if anyone needs a support for TS <4.5, there is a self implementation of Awaited
from ts-throwable.
@adrianwiechec-at-optilyz fixed on master, TS playground here
from ts-throwable.
Works splendidly now, thanks very much! 🙇
