Error while creating a stream to listen to notifications

[ankita410]

We have started the docker container with jar of 'lighty-notifications-device' from lighty-netconf-simulator. Added a device , and was able to create-subscription and then trigger-notification using RestConf by integrating the NETCONF simulator device into Lighty RNC.
Post trigger notification, we are trying to create a stream to listen to the notifs using curl --request POST \ --url http://localhost:8888/restconf/operations/odl-device-notification:subscribe-device-notification \ --header 'content-type: application/json' \ --data '{ "input": { "path": "/network-topology:network-topology/topology[topology-id='\''topology-netconf'\'']/node[node-id='\''notification-device'\'']" } }'

Response we get - { "errors": { "error": [ { "error-tag": "operation-failed", "error-message": "No implementation of RPC (urn:opendaylight:device:notification?revision=2024-02-18)subscribe-device-notification available", "error-type": "rpc" } ] } }

Can you help us the identify the issue?

Hi, Giving some more inputs on the issue - Started example lighty-notifications-device from lighty-netconf-simulator. Its exposes lighty-test-notifications yang.
Apis working through Restconf -

1. Add a device -

2. Create subscription
   Api used - curl --request POST \ --url http://127.0.0.1:8888/restconf/operations/network-topology:network-topology/topology=topology-netconf/node=notification-device3/yang-ext:mount/notifications:create-subscription \ --header 'content-type: application/yang-data+json'

3. Trigger Notification
   Api used - curl --request POST \ --url http://127.0.0.1:8888/restconf/operations/network-topology:network-topology/topology=topology-netconf/node=notification-device3/yang-ext:mount/lighty-test-notifications:triggerDataNotification \ --header 'accept: application/yang-data+json' \ --header 'content-type: application/json' \ --data '{ "input": { "ClientId": 1, "Count": 1, "Delay": 0, "Payload": "Test Notification 5" } }'

4. Now we want to create a stream to listen to the notifs . Api we are using is curl --request POST \ --url http://localhost:8888/restconf/operations/odl-device-notification:subscribe-device-notification \ --header 'content-type: application/json' \ --data '{ "input": { "path": "/network-topology:network-topology/topology[topology-id='\''topology-netconf'\'']/node[node-id='\''notification-device'\'']" } }' but we get error - No implementation of RPC (urn:opendaylight:device:notification?revision=2024-02-18)subscribe-device-notification available

Any idea what can be done about it?
