Turn on a Simple LED in device with a button in Dashboard

Turn on a Simple LED in device with a button in Dashboard

Hello, 
I'm trying to turn on a LED on my device which is a Linux box. 
I used the guide provided by the Help and the Python template code. 
However, when I press the button, following error is reported in Analysis console:
