Handling `FiberFailure` Instead of Expected Error
Hey
! A question about error handling
: I have an effect that returns an error
FetchNotFound
FetchNotFound
when getting a 404 response
, the problem I have is when I use
Effect.runPromise
Effect.runPromise
. I expect to find a
FetchNotFound
FetchNotFound
error
catch
catch
ing the promise
, instead I get a
FiberFailure
FiberFailure
, anyone know how to return the original error
?
