### Description hello. as this issue methioned: [#5607](https://github.com/apache/apisix/issues/5607) I also suffered such a situation. but I can not reproduce it. the error log is : ` /traffic-split.lua:209: attempt to index field 'upstream' (a string value) ` according the source code. when the traffic-split plugin config "weighted_upstreams" . it's element has no property "upstream". but have property "upstream_id", it should not invode the follwing code (line 209, because **elseif upstream_obj.upstream then** return false )  so I confused why line 209 is invoked. traffic_split config is below: ` { "traffic-split": { "disable": false, "rules": [{ "weighted_upstreams": [{ "weight": 0 }, { "upstream_id": "466807194923303750", "weight": 100 }, { "upstream_id": "466807194721978186", "weight": 0 }] }] } } ` ### Environment - APISIX version (run `apisix version`): v2.12.0 - Operating system (run `uname -a`): - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):3.5.0 - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
