mgmtd: problem with commits

[ak503]

Description

I have simple config:

ip route 1.2.3.4/32 192.168.1.1

After # mgmt save-config running /tmp/frr.rc I getting file frr.rc:

{
  "frr-routing:routing": {
    "control-plane-protocols": {
      "control-plane-protocol": [
        {
          "type": "frr-staticd:staticd",
          "name": "staticd",
          "vrf": "default",
          "frr-staticd:staticd": {
            "route-list": [
              {
                "prefix": "1.2.3.4/32",
                "afi-safi": "frr-routing:ipv4-unicast",
                "path-list": [
                  {
                    "table-id": 0,
                    "distance": 1,
                    "frr-nexthops": {
                      "nexthop": [
                        {
                          "nh-type": "ip4",
                          "vrf": "default",
                          "gateway": "192.168.1.1",
                          "interface": "(null)"
                        }
                      ]
                    }
                  }
                ]
              }
            ]
          }
        }
      ]
    }
  },
  "frr-vrf:lib": {
    "vrf": [
      {
        "name": "default"
      }
    ]
  }
}

But after loading this conf-file on empty configuration I have problems:

# configure terminal file-lock 
(config)# mgmt load-config /tmp/frr.rc replace
(config)# mgmt commit check
ERROR: COMMIT_CONFIG request failed, Error: YANG error(s):

On frr-9.1 in is not reproduced

How to reproduce

1. create config:

ip route 1.2.3.4/32 192.168.1.1

2. save to file via mgmtd:

# mgmt save-config running /tmp/frr.rc

3. run frr with empty config
4. load config from file /tmp/frr.rc via mgmtd:

# configure terminal file-lock
(config)# mgmt load-config /tmp/frr.rc replace

5. check commit (or apply):

(config)# mgmt commit check

Expected behavior

no error

Actual behavior

# configure terminal file-lock 
(config)# mgmt load-config /tmp/frr.rc replace
(config)# mgmt commit check
ERROR: COMMIT_CONFIG request failed, Error: YANG error(s):
 Path: Data location "/ietf-yang-schema-mount:schema-mounts".
 Error: Unexpected data state node "schema-mounts" found.
 Path: Data location "/frr-vrf:lib/vrf[name='default']/state".
 Error: Unexpected data state node "state" found.
 Path: Data location "/frr-vrf:lib/vrf[name='default']/state/active".

Additional context

on frr 9.1 after this steps i can apply config without problems
