After changing to v2beta3, I succed to create uptream, but it didn't work.
I want to proxy grpc and use plaintext(no tls):
This is my svc:
```
kubectl get svc -n vector
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S)
AGE
vector ClusterIP a.b.c.d <none>
9598/TCP,6788/TCP 6d8h
vector-headless ClusterIP None <none>
9598/TCP,6788/TCP 6d8h
```
This is my route.yaml
```yaml
apiVersion: "apisix.apache.org/v2beta1"
kind: ApisixRoute
metadata:
namespace: vector
name: otel-log-route
spec:
http:
- name: otel-log-ingester
match:
paths:
- "/opentelemetry.proto.collector.logs.v1.LogsService/Export"
hosts:
- camp.apisix.woa.com
backend:
serviceName: vector
servicePort: 6788
```
and this is upstream.yaml
```yaml
apiVersion: apisix.apache.org/v2beta3
kind: ApisixUpstream
metadata:
namespace: vector
name: vector
spec:
scheme: grpc
```
When I curl domain/opentelemetry.proto.collector.logs.v1.LogsService/Export,
ingress-controller panic
```
panic: runtime error: index out of range [0] with length 0
goroutine 137 [running]:
