This line of code causes the bug.

Because etcd key has the prefix in default config. Use below code to solve this bug:
```
local key = "/routes/"
local local_conf = core.config.local_conf()
if local_conf.etcd and local_conf.etcd.prefix then
key = local_conf.etcd.prefix .. key
end
local res, _ = config:getkey(key)
```
