bare time signature rendering difference

[Nate]

I seem to have some sort of platform difference between my desktop and laptop computers. I'm rendering a bare time signature and tempo in a LaTeX table using lyluatex.

The snippet:

\lilypond[noindent, nofragment]

  { \new RhythmicStaff \with {\remove "Staff_symbol_engraver"}
  { \time 6/8 \numericTimeSignature  \tempo 4=120  }}

renders as expected with lualatex --shell-escape ts.lytex

(LuaTex v 1.10.0 TeX Live 2019/Debian)

LaTeX2e 2020-02-02 patch level 2

However my desktop appears to have
This is LuaHBTeX, Version 1.12.0 (TeX Live 2020/Debian)

LaTeX2e <2020-10-01> patch level 4

installed, and fails to render any output:

Module lyluatex Warning: The score doesn't contain any music:
(lyluatex)               this will probably cause bad output

Is this properly formatted code?
