For safety use, it's better to have null check for all variables which are used in this function.

if (!_sessionPriv.$clientAlarmList) {
    return;
}

↓

if (!_sessionPriv.$clientAlarmList
     || !_sessionPriv.$monitoredItemForAlarmList
     || !_sessionPriv.$subscriptionforAlarmList ) {
    return;
}

-Preferably a setting on JsonRpc itself that produce error when AddLocalRpcTarget is called
-A setting on JsonRpc itself that produce error during

The documentation can be added to: https://napalm-logs.com/en/latest/syslog/index.html - help would be greatly appreciated.
