   I've tried to locate it by adding some `core.log.info(...)`
   
   Find the root statement is at https://github.com/apache/apisix/blob/master/apisix/core/etcd.lua#L188
   
   Trying to call `etcd_cli:set()` with key `/apisix/plugins` and value of plugins name list (mine is  `[{"name":"echo"}]`) and failed.
   
   the current logic `if not res` cannot detect this failure, because the `error` field stays inside the `res` body.
