How to enable an error message when user tries to delete a record that doesnt exist? confd says “No modifications to commit” after user commits, but is there a way to trigger an error as soon as user tries to delete/change a value that doesnt exist in the CDB?

root@cavium-thunderx 21:31:43% show link vlan-map
vlan-map 0 {
    vid [ 3 100 200 ];
}

No modifications to commit.

You basically asked the same question and got an answer 6 months ago:
Displaying error message when user tries to delete something that doesnt exist in DB?
