Apicast logs these warn messages on startup. They are harmless but noisy, several customers have noticed them and are had asked.
According to this OpenResty issue, it won't be logged when the global variables are changed to local variables, or add rawset(_G, '<variable>', false) before including the variable.
So please suppress the messages.
