In *Eberron: Rising from the Last War* (p. 36), the [warforged's Constructed Resilience trait](https://www.dndbeyond.com/races/warforged#WarforgedTraits) includes the following benefit:

> 
> You don’t need to sleep, and magic can’t put you to sleep. 
> 
> 
> 

The Sentry's Rest trait also says:

> 
> When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal.
> 
> 
> 

Now, I've noticed that this is a change from the original version of *Wayfinder's Guide to Eberron*, in which the corresponding benefit of the warforged's Warforged Resilience trait (p. 68) read:

> 
> You don’t need to sleep and *don’t suffer the effects of exhaustion due to lack of rest*, and magic can’t put you to sleep.
> 
> 
> 

In the final version of warforged, if this living construct refused to take a long rest, would it suffer exhaustion that a normal humanoid of the flesh would likely take? Or would it be safe from that kind of exhaustion?
