Aborting Nginx reload on condition

[Rockybilly]

Hello, is there a way with lua that, upon checking a condition, abort an nginx reload with error, so the old conf keeps running.

I have this in my xxx_by_lua_block codes in the conf:
local m = require(module)

if this fails, all the requests in the server becomes HTTP 500. This fails obviously because of an error in the lua code, however to be extra careful I want to prevent reload if an error can be found before the worker starts running.
