### Current Behavior When modify nodes weight, error log will be recorded " all upstream nodes is unhealthy" ### Expected Behavior no error log ### Error Logs  `2025/01/07 18:04:23 [error] 6714#6714: *276732 [lua] balancer.lua:83: fetch_health_nodes(): failed to get health check target status, addr: 10.58.94.168:80, host: nil, err: target not found, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" 2025/01/07 18:04:23 [error] 6714#6714: *276732 [lua] balancer.lua:83: fetch_health_nodes(): failed to get health check target status, addr: 10.58.32.145:80, host: nil, err: target not found, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" 2025/01/07 18:04:23 [warn] 6714#6714: *276732 [lua] balancer.lua:89: fetch_health_nodes(): all upstream nodes is unhealthy, use default, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" 2025/01/07 18:04:24 [error] 6716#6716: *276683 [lua] balancer.lua:83: fetch_health_nodes(): failed to get health check target status, addr: 10.58.32.145:80, host: nil, err: target not found, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" 2025/01/07 18:04:24 [error] 6716#6716: *276683 [lua] balancer.lua:83: fetch_health_nodes(): failed to get health check target status, addr: 10.58.94.168:80, host: nil, err: target not found, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" 2025/01/07 18:04:24 [warn] 6716#6716: *276683 [lua] balancer.lua:89: fetch_health_nodes(): all upstream nodes is unhealthy, use default, client: 127.0.0.1, server: _, request: "GET /l HTTP/1.1", host: "l.com" ` ### Steps to Reproduce 1. create a route and upstream with 2 or more nodes. Upstream need turn on healthcheck   2. run a wrk command to make requests to the server continuously.  3. change node weight continuously(such as keep executing the following command) `curl -XPATCH -s -H "x-api-key: $token" http://192.168.20.226:9180/apisix/admin/upstreams/547982406942985081 -d '{"nodes":{"10.58.32.145:80": 20}}'` 4. and we will get error log  5.In extreme cases, client will get a 500 internal error(but this cannot be reproduced stably)  ### Environment - APISIX version (run `apisix version`): 3.5 - Operating system (run `uname -a`): 3.10.0-514.26.2.el7.x86_64 - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): openresty/1.21.4.2 - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): 3.5 - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): 2.3.0 -- This is an automated message from the Apache Git Service.
