Runtime error: no request found

[psxde]

Hi,

I have...

1. Installed nginx-mod-http-lua and lua-resty-http on a running Alpine nginx installation
2. Downloaded cas.lua and global_cas_conf.lua to /etc/nginx/lua
3. Configured cas_uri in /etc/nginx/lua/global_cas_conf.lua
4. Configured nginx.conf

But get an Internal Server error calling the protected path. The error log of nginx reports:

2021/06/06 20:48:48 [error] 2352#2352: *2 lua entry thread aborted: runtime error: /usr/share/lua/common/resty/core/var.lua:71: no request found

Do you have some hints?

Thanks,
Patrick

nginx-auth-cas-lua is tested on debian which has ngx_http_lua_module 0.10.13, which has C implementation of ngx.var.

It seems you have lua-resty-core which is a lua implementation of things previously done in C (cf https://github.com/openresty/lua-resty-core#description ). It would be great to make nginx-auth-cas-lua work on more recent versions, but I can't help for now.
