This could be the problem, registering classes is usual in .pd_lua files
but not .pd_luax files.

where did you define get_word_from_inlet? You should just be able to
use 's', as that's the symbol atom passed to the inlet method.

This seems to be a Lua problem more than a pdlua problem - you use
get_word_from_inlet() but don't define it anywhere.
A pdlua manual is on my todo list, but for now the examples are the best
