Sorry to disturb again, I've just added a ui_dropdown node so that I can specify the type of item. However, after adding the ui_dropdown, some errors just popped out.
This error pop out when I'm filling in the form:
'Message missing key property 'msg.topic' - cannot add to object'
I've looked through the other page for reference on how I should configure my ui_dropdown: How to retrieve data from ui dropdown on button click still can't seem to get it working as intended.
Once again, thanks in advance for your help.
