Los paquetes LUA instalados son lua-cjson luaffi lua-resty-http lua-resty-jwt lua-resty-openidc lua-resty-session

Espero haber instalado los paquetes requeridos de lua, puede que el problema esté en el archivo de configuración de nginx en la línea 25 local res, err = require("resty.openidc").authenticate(opts)
