❔ Can't catch Unity Coroutine (IEnumerator) error

Hi! I'm running some Func inside a Unity Coroutine. I'm using an approach I've used before to get the errors the code might throw and handle them, but by some reason, I can't catch the errors. You guys have any idea why?

This is the code that runs inside the Coroutine and executes a list of actions, theorically handling any error thrown ^ I've used this "trick" before, and it worked (not on this project):

                            try
                            {
                                next = enumerator.MoveNext();
                            }
                            catch (Exception e)
                            {
                                exception = e;
                                goto onError;
                            }
                             if (next)
                            {
                                yield return enumerator.Current;
                            }

                            try
                            {
                                next = enumerator.MoveNext();
                            }
                            catch (Exception e)
                            {
                                exception = e;
                                goto onError;
                            }
                             if (next)
                            {
                                yield return enumerator.Current;
                            }

YieldInvoke code:

       public readonly Func<T, IEnumerator> Func;
       public readonly T Context;

       public IEnumerator YieldInvoke()
        {
            var awaitable = Context as IAwaitable;
            if (awaitable != null)
            {
                awaitable.Completed = false;
            }
            yield return Func(Context);
            if (awaitable != null)
            {
                awaitable.Completed = true;
            }
        }

       public readonly Func<T, IEnumerator> Func;
       public readonly T Context;

       public IEnumerator YieldInvoke()
        {
            var awaitable = Context as IAwaitable;
            if (awaitable != null)
            {
                awaitable.Completed = false;
            }
            yield return Func(Context);
            if (awaitable != null)
            {
                awaitable.Completed = true;
            }
        }

I can't try-catch a Func inside an IEnumerator, is that it?

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
