As we discussed, we are encountering an issue with the Gaming ADD-ON scenario for orders where no trail is available. These orders are failing with the following error:
CVlan Reservation failed - Couldn't find active node while calling reserveCvlanIp API.

Currently, the NEP system attempts to extract active node details from the trail when calling this API. Since these specific orders lack trail data, they are being interrupted.

Recommendation: I suggest implementing a fallback logic. If the trail is unavailable, NEP should automatically pull the active node details from the ONU view. This will ensure the API call succeeds and prevents the CVlan reservation error.
