Firstsawyou opened a new issue #3108: URL: https://github.com/apache/apisix/issues/3108
### Issue description When the `limit-count` plugin is enabled on `service` and `upstream` is the domain name. This will cause the `local key = (ctx.var[conf.key] or "") .. ctx.conf_type .. ctx.conf_version` generated in the limit-count plugin to be inconsistent. When `ctx.conf_version` is deleted (`local key = (ctx.var[conf.key] or "") .. ctx.conf_type`), the plug-in function returns to normal. Steps to reproduce, will be added later. ### Environment * apisix version (cmd: `apisix version`): 2.1 * OS: (cmd: `uname -a`)：centos7 * OpenResty / Nginx version: (cmd: `nginx -V` or `openresty -V`): openresty/1.19.3.1 ### Minimal test code / Steps to reproduce the issue 1. 2. 3. ### What's the actual result?
