Description

When trying to configure PIMv6 via Northbound gRPC, seeing error message [WH5BW-RNTXW][EC 100663326] nb_running_get_entry_worker: failed to find entry [xpath /frr-interface:lib/interface[name='eth0']/frr-pim:pim/address-family[address-family='frr-routing:ipv6']]

Version

# show version
FRRouting 10.1 (host) on Linux(6.6.51).
Copyright 1996-2005 Kunihiro Ishiguro, et al.

How to reproduce

  1. Enable Northbound gRPC, and specify opts -M grpc for pim6d in /etc/frr/daemons file
  2. Use client code to edit a candidate request to enable PIM on an interface, (e.g. in golang):
conn, err := grpc.NewClient("localhost:50051", grpc.WithTransportCredentials(insecure.NewCredentials()))
if err != nil {
	return err
}

cli := frr.NewNorthboundClient(conn)

ctx := context.Background()

newCandidate, err := cli.CreateCandidate(ctx, &frr.CreateCandidateRequest{})

editReq := &frr.EditCandidateRequest{}
editReq.CandidateId = newCandidate.GetCandidateId()
interfacePath := "/frr-interface:lib/frr-interface:interface[name='eth0']/frr-pim:pim/address-family[address-family='frr-routing:ipv6']/pim-enable"
editReq.Update = append(editReq.Update, &frr.PathValue{Path: interfacePath, Value: "true"})
r, err := cli.EditCandidate(ctx, editReq)
if err != nil {
	return err
}
	
commitReq := &frr.CommitRequest{}
commitReq.CandidateId = newCandidate.GetCandidateId()
commitReq.Phase = frr.CommitRequest_ALL
commitReq.Comment = "Add pim6 to interface " + interfaceName
if _, err = cli.Commit(ctx, commitReq); err != nil {
	return err
}

Expected behavior

Expect to see gRPC success (exit code 0) and updated interface with ipv6 pim enabled in the running configuration

Actual behavior

Seeing crash with following backtrace:
