Reset is not working with count.md code

[darpangupta12]

For Nginx rate limiting, we are using code written on count.md. Also, we are using count.lua library.
Below code, giving counter value from 199 to 1 from line
local delay, err = lim:incoming(key, true)
After that, above line giving rejected error hence, it returning 503 error.
So, reset is not working in time_window & getting rejected value in err.Please check count.lua library as well.

Refer Code :-
local lim, err = limit_count.new("my_limit_count_store", 200, 1)
ngx.log(ngx.ERR, "lim instance value: ", err)
if not lim then
--ngx.log(ngx.ERR, "failed to instantiate a resty.limit.conn object: ", err)
return ngx.exit(500)
end
--if header_authorization then
local base64_enc = string.sub(header_authorization, 7)
local base64_dec = ngx.decode_base64(base64_enc)
ngx.log(ngx.ERR, "base64_dec value: ", base64_dec)
local key = base64_dec
local delay, err = lim:incoming(key, true)
ngx.log(ngx.ERR,"new instance value: ",err)

      if not delay then
                if err == "rejected" then
                    ngx.log(ngx.ERR, "coming to this block: ", err)
                    ngx.header["X-RateLimit-Limit"] = "200"
                    ngx.header["X-RateLimit-Remaining"] = 0
                    return ngx.exit(503)
                end
          --      ngx.log(ngx.ERR, "failed to limit req: ", err)
                return ngx.exit(500)
      end

    local remaining = err
    ngx.log(ngx.ERR, "remaining value: ", remaining)

    ngx.header["X-RateLimit-Limit"] = "200"
    ngx.header["X-RateLimit-Remaining"] = remaining
    ngx.log(ngx.ERR, "X-RateLimit-Remaining: ", ngx.header["X-RateLimit-Remaining"])
