Symptom

The next error is shown when we run gNMI query adding "next-hop-self": ``` The error is: pygnmi.client.gNMIException: GRPC ERROR Host: jfk-edge01.doubleverify.prod:57777, Error: { "cisco-grpc:errors": { "error": [ { "error-type": "application", "error-tag": "operation-failed", "error-severity": "error", "error-path": "Cisco-IOS-XR-um-router-bgp-cfg:router/bgp/as[as-number = 'AS-Num']/neighbors/neighbor[neighbor-address = 'x.x.x.x']/address-families/address-family[af-name = 'ipv4-unicast']/next-hop-self", "error-message": "'sysdb' detected the 'warning' condition 'A verifier or EDM callback function returned: 'not found''" } ] } } ```

Conditions

When customer is running 7.9.x adding "next-hop-self" e.g.: ``` { "neighbor-address": "x.x.x.x", "address-families": { "address-family": [ { "af-name": "ipv4-unicast", "maximum-prefix": {}, "route-policy": { "in": "IN_POLICE", "out": "OUT_POLICE" }, "send-community-ebgp": {}, "next-hop-self": {} >>>> } ] } ``` *** Whenever we remove "next-hop-self" query works with no further error.

Workaround

We can try with the Native query model: Native Model: Cisco-IOS-XR-ipv4-bgp-cfg/bgp/instance[instance-name]/instance-as[as]/four-byte-as[as]/default-vrf/bgp-entity/neighbors/neighbor[neighbor-address]/neighbor-afs/neighbor-af[af-name]/next-hop-self
