Hi,
You are using the instance name and the command needs the node pool name which is in your command should be "ulsin1002"
Hope this helps
These are nodepool:
NAME STATUS ROLES AGE VERSION
aks-ulsin1002-42505972-vmss000000 Ready agent 55d v1.25.6
aks-ulsin1002-42505972-vmss000001 Ready agent 55d v1.25.6
aks-ulsin1002-42505972-vmss000012 Ready agent 53d v1.25.6
I have to restart only --> aks-ulsin1002-42505972-vmss000001

These are nodes and the command you are using is to stop the node pool itself.
To list the node pools, you can use this command line:
az aks nodepool list --cluster-name AKSname -g ResourceGroupName -o table
If you would like to reboot one instance then you can navigate to the VMSS from Azure portal and select the instance and reboot it, or you can use these commands to SSH to the node and reboot it:
kubectl debug node/aks-ulsin1002-42505972-vmss000001 -it --image=mcr.microsoft.com/dotnet/runtime-deps:6.0
chroot /host /bin/bash
reboot
