No it sounds broken on whatever you're using.  But whatever you're using is 5 years old, and this was fixed on that kind of timescale.

Update lws, in addition to this working, I'll care about bugs on main and last stable, currently v4.2.

It sounds from the inexact lws version you don't follow the -stable branch for your release either, that's something since v1.5 that's another opportunity to get fixes that are found in the months after the release, without introducing new features or api changes.

There's an explanation of this here
