How to avoid program getting stuck when forget using utcs.TrySetResult()?

[zrp2016]

See code as following:

public static UniTask GetUTCSUniTask(Action<UniTaskCompletionSource> callback)
{
    var src = GetUTCS();
    if (callback!=null)
    {
        callback?.Invoke(src);
    }
    else
    {
        src.TrySetResult();
    }

    return src.Task;
}

As I set the param callback having await operations in it,then I await the unitask returned by this func,when I forget setting x.TrySetResult(),and this awaiting snippet will be stunning, it's common.
So how can I avoid this stunning and get exceptions

I don't know what you mean by "stunning", but you can overload the function to take an async callback.

public static async UniTask GetUTCSUniTask(Func<UniTaskCompletionSource, UniTask> callback)
{
    var src = GetUTCS();
    if (callback != null)
    {
        await callback.Invoke(src);
    }
    else
    {
        src.TrySetResult();
    }

    await src.Task;
}

    {
        await callback.Invoke(src);
    }
    else
    {
        src.TrySetResult();
    }

    await src.Task;
}

"stunning" means program running is stucked，and I don't want GetUTCSUniTask to be an async func,it only returns unitask,as I want to set callback for this func , calling this func and await it.

There's no way to determine what causes your program to get stuck from that code. You'll have to share more.

when forget using utcs.TrySetResult()

Oh, the answer is in your title. Obviously if you never set the task it will never continue. Just don't forget to do that. UniTask has a task tracker that you can use to find those types of forever tasks.

yeach, I can track by using it in editor,but I don‘t want the program get stuck,how about the following:

public static UniTask GetUTCSUniTask(Action<UniTaskCompletionSource> callback)
{
    var src = GetUTCS();
    if (callback!=null)
    {
        callback?.Invoke(src);
        // avoid getting stuck
        UniTask.Delay(2).ContinueWith(()=>
        {
            if (!src.Task.Status.IsCompleted())
            {
                src.TrySetException(new TimeoutException("The operation timed out."));
            }
        }).Forget();
    }
    else
    {
        src.TrySetResult();
    }

    return src.Task;
}

I just want to know where I miss setting when not running in editor
