Current Behavior

I followed the guide: https://apisix.apache.org/docs/apisix/plugins/wolf-rbac/
When I using a wrong password, the apisix returned:

{"message":"request to wolf-server failed!"}

and from the apisix logs:

2025/05/19 08:41:09 [error] 64#64: *112501465 [lua] wolf-rbac.lua:381: request_to_wolf_server(): request [{"reason":"ERR_PASSWORD_ERROR","ok":false,"data":{}}] failed! response body:{"reason":"ERR_PASSWORD_ERROR","ok":false,"data":{}}, client: XXXX server: _, request: "POST /auth/token HTTP/1.1", host: "devicbc.XXXX.cn:88"
2025/05/19 08:41:09 [info] 74#74: *112501656 [lua] timers.lua:39: run timer[plugin#server-info], context: ngx.timer

Expected Behavior

The error should make it sense when some known errors found from wolf.

Error Logs
