Whatever I do, I always get nil

[alexanschiffer]

This is the error from error log:

2024/04/02 18:02:08 [error] 7#0: *1 [lua] whitelist.lua:96: failed to instantiate a rest1111111: nil, client: 172.22.0.5, server: _, request: "GET / HTTP/1.1", host: "domain.tld"
2024/04/02 18:02:08 [error] 7#0: *1 invalid URL prefix in "fine", client: 172.22.0.5, server: _, request: "GET / HTTP/1.1", host: "domain.tld"

This is lua code. The goal is to check if rate limit is reached. If the rate limit is reached, then it should run the code and if not, the else block:

-- First check for rate limit
local limit_count = require "resty.limit.count"
local lim, err = limit_count.new("my_limit_count_store", 20, 60)

--if rate limited run application
if not lim then
ngx.log(ngx.ERR, "failed to instantiate a resty.limit.count object: ", err) -- This is done for testing if this gets called


(...) -- some lua code which already work
else
        ngx.log(ngx.ERR, "failed to instantiate a rest1111111: ", err)
        ngx.var.check = "fine"
end

the http block contains:

        lua_shared_dict my_req_store 100m;
        lua_shared_dict my_conn_store 100m;
        lua_shared_dict my_limit_conn_store 100m;
        lua_shared_dict my_limit_req_store 100m;
        lua_shared_dict my_limit_count_store 100m;

    init_by_lua_block {
        require "resty.core"
    }

Whatever I do, I always get the same error. I already tried

if not lim then
to
if lim then

and

local limit_conn = require "resty.limit.conn"
local lim, err = limit_conn.new("my_limit_conn_store", 10, 10, 0.5)

but always with the same result.
