IOT Link Publish Not Working

Trying to get my PC to lock using IOT Link but it’s not working.

IOT is correctly connected to MQTT and I can see all the respective entities and information.

However:

service: mqtt.publish
data:
  topic: "iotlink/WORKGROUP/DUMONSTERPC/commands/lock"
  payload: ""

Doesn’t do anything.

What am I doing wrong?

Assuming you are properly connected, try everything in lowercase, i have this as “topic” and it works fine

iotlink/workgroup/desktop-gaming/commands/shutdown

That fixed it. Thanks!
