helm install apisix, but kubernetes discovery disable

[xplusadmin]

helm upgrade --install apisix apisix/apisix \
--create-namespace \
--namespace apisix \
--set dashboard.enabled=true \
--set-string dashboard.config.authentication.users[0].password=admin \
--set-string dashboard.config.authentication.users[0].username=admin \
--set ingress-controller.enabled=true \
--set apisix.prometheus.enabled=true \
--set gateway.type=LoadBalancer \
--set-string admin.allow.ipList="{0.0.0.0/0}" \
--set apisix.discovery.enabled=true \
--set-string apisix.discovery.registry.kubernetes="{}" \
--set ingress-controller.config.apisix.adminAPIVersion=v3 \
--set ingress-controller.config.apisix.serviceNamespace=apisix

i used the above command to install apisix,but found some problems:

1. kubernetes discovery ，but pod apisix not running, logs：invalid discovery kubernetes configuration: object matches none of the required
2. i follow wikihttps://apisix.apache.org/zh/docs/apisix/discovery/kubernetes, use command <kubectl edit configmaps apisix -n apisix -o yaml> change config：
   discovery:
   kubernetes: { }
   pod apisix is running, but i couldn't find any kubernetes endpoints
3. use command(kubectl exec -it apisix-5bd655f5b6-phfw5 -n apisix -- curl -i -X GET "http://localhost:9180/apisix/admin/upstreams" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1"), i couldn't find nothing

How can i fix this?
