subscribe notification with xpath-filter is throwing error at netopeer-server #1447

Closed kavk7 closed 11 months ago

kavk7 commented 1 year ago

Hi Team,

On netopeer2-cli, subscribing for notifications with following xpath filter is throwing error at netopeer-server. Though netopeer2-cli outputs "OK" but no notification comes on edit-config. unable to find where "instance-identifier" type is defined and its supported pattern. Please help in how to subscribe for specific xpath edit-config notifications.

sysrepo : 2.2.7 netopeer2 : 2.1.41 libyang : 2.0.263 libnetconf2 : 2.1.25

subscribe --filter-xpath /ietf-netconf-notifications:netconf-config-change/edit[target="/urn:hb-mgmt:1.0:hb"] OK
