regend opened a new issue, #2576:
URL: https://github.com/apache/apisix-ingress-controller/issues/2576
### Current Behavior
When one of the routers in APISIX is configured with a Kubernetes service
whose endpoint does not exist (e.g., due to misconfiguration or other reasons),
it causes the entire APISIX instance to malfunction, and the ingress logs show
the following error:
`2025-09-24T03:31:58Z error adc/adc.go:431 failed to execute adc
command {"error": "ADC execution error for apisix/apisix-config: [ServerAddr:
http://apisix-admin.apisix:9180, Err: failed to sync resources: Error: Lint
configuration\nThe following errors were found in configuration:\n#1 Expected
array, received null at service: \"dev2_dev2-xqd-biz-base-censor_0-1\", field:
\"upstream.nodes\"\n#2 Expected array, received null at service:
\"dev2_dev2-xqd-biz-base-censor_0-0\", field: \"upstream.nodes\"\n, exit err:
exit status 1]", "config":
{"name":"apisix/apisix-config","serverAddrs":["http://apisix-admin.apisix:9180"],"tlsVerify":false}}`
### Expected Behavior
Expected behavior: If a single router's service configuration is incorrect,
only that specific router should be affected, without impacting the entire
APISIX instance globally.
### Error Logs
_No response_
### Steps to Reproduce
1. update k8s service make it wrong and endpoint not exist
2. watch ingress-controller logs
### Environment
- APISIX Ingress controller version (run `apisix-ingress-controller version
--long`)
- Kubernetes cluster version (run `kubectl version`)
- OS version if running APISIX Ingress controller in a bare-metal
environment (run `uname -a`)
apisix:3.13.0
apisix-ingress-controller:2.0.0-rc3
