Hello!
I'm converting my home from ST to HE, and first off, man, Loving HE! So fast, and so easy! Everything just works! = )
But I'm having issues porting a driver over from ST. I wrote it for a App I wrote "Smart Room". My App ported over just fine, but when I try to save the Driver, I get the error:
Cannot get property 'label' on null object on line 19
I searched the forum for that error, but wasn't able to pull anything applicable from what I read. Line 19 is the 'metadata' line in the below code.
Does anyone have any insights into what I'm doing wrong?
Thanks for your time,
Nick
