Hi,

It seems like you are using an unreleased version of lua-resty-core. To
fix this error, you will need to use a version of lua-nginx-module that
has this commit:

https://github.com/openresty/lua-nginx-module/commit/1c72f57ce87d4355d546a97c2bd8f5123a70db5c

A bump of the min ngx_lua dependency is soon to be made in lua-resty-core.

Overall, I strongly suggest that you use official OpenResty releases
instead (the latest one presently being 1.13.6.2. If you must use
unreleased features of lua-resty-core, then I suggest that if possible,
you use an rc tag (the latest one currently being v0.1.16rc3), along
with the ngx_http_lua version that is compatible with it.

Best,
Thibault
