Switches are working but lock is not working

[naseemr]

Hi, In HASS, I have the following for lock, but I cannot lock/unlock through homeassistant. But I am able to turn on switch/lights. lock:

• platform: mqtt name: "Front Door" state_topic: "smartthings/Front Door/lock" command_topic: "smartthings/Front Door/set" payload_lock: "LOCKED" payload_unlock: "UNLOCKED"

switch:

• platform: mqtt name: "Lamp" state_topic: "smartthings/Lamp/switch" command_topic: "smartthings/Lamp/switch" payload_on: "on" payload_off: "off" retain: true

This is what is working for me:

state_topic: "smartthings/Front Door/lock"
command_topic: "smartthings/Front Door/lock"
payload_lock: "locked"
payload_unlock: "unlocked"
