prob setting a compressor (zlib)

[AramshamFedaykin]

Hello,

I tried to add a compressor in an nginx ingress controller via set $session_compressor zlib;, but I get this error :

lua entry thread aborted: runtime error: /usr/local/share/lua/5.1/resty/session.lua:569: attempt to index local 'com' (a number value)
stack traceback:
coroutine 0:
/usr/local/share/lua/5.1/resty/session.lua: in function 'new'
/usr/local/share/lua/5.1/resty/session.lua:581: in function 'open'
/usr/local/share/lua/5.1/resty/session.lua:621: in function 'start'
/usr/local/share/lua/5.1/resty/openidc.lua:1708: in function 'authenticate'
access_by_lua(nginx.conf

I installed lua-ffi-zlib and penlight via luarocks in my dockerfile.

env :
k8s v1.21.9
nginx-ingress-controller v1.5.1 (nginx 1.21.6)

Is it a path problem or something else ? Could you please take a look at this ?

I got the exact same error

lua entry thread aborted: runtime error: /usr/share/lua/common/resty/session.lua:566: attempt to index local 'com' (a number value)
stack traceback:

/usr/share/lua/common/resty/session.lua: in function 'new'

/usr/share/lua/common/resty/openidc.lua:1470: in function 'authenticate'
/etc/nginx/sso.lua:54: in function 'sso_auth'

env:
alpinelinux
nginx version: nginx/1.22.1
lua-resty-session v3.8

Any ideas?

In my case it was a missing dependency... the error message is very misleading though.

Oh ! Good to know, could you please tell me what was your missing dependency ?

For my part, I hesitated to continue on the old version, but as long as openidc.lua is using it...
