Bad "zone" argument

[abraae]

I have the following problem with both alpine and debian flavours when clicking "Try this link" in the example application:

2016/05/07 10:04:50 [error] 7#0: *1 lua entry thread aborted: runtime error: /opt/openresty/nginx//lualib/resty/shcache.lua:429: bad "zone" argument

how to slove the problem?

local function check_zone(zone)
    if not zone or type(zone) ~= "table" then
        error("bad \"zone\" argument", 2)
    end

    zone = zone[1]
    if type(zone) ~= "userdata" then
        error("bad \"zone\" argument", 2)
    end

    return zone
end

I think you use shard.get but you must use shard:get
