Once the said file https://raw.githubusercontent.com/authzed/spicedb/main/k8s/example.yaml is applied, I enabled port-forward on one of the pod, but unable to get the check api working , all delete , create api works fine. Am I missing something? the request just times out - name: "SPICEDB_DISPATCH_UPSTREAM_ADDR" value: "kubernetes:///spicedb:dispatch" is "dispatch" as per the sample example file here refers to namespace ?
