Missing namespace for module's state list node (inner-state-bean)

Yang module snippet:

augment "/config:modules/config:module/config:state" {
case pcep-topology-provider {
when "/config:modules/config:module/config:type = 'pcep-topology-provider'";
list listener-state {
description "Statistics gained from session listener.";
config:inner-state-bean;
rpcx:rpc-context-instance "session-rpc";

key "peer-id";

leaf peer-id

whole config yang module: https://jenkins.opendaylight.org/bgpcep/job/bgpcep-merge/ws/pcep/topology-provider/src/main/yang/odl-pcep-topology-provider-cfg.yang/*view*/
