Find wand issue

[BranTechnology]

Hello I have the hue.pay file just looking for the wand copying exactly the same code from your blog and it worked the first time it discovered the wand but today I woke up to continue coding it and now it gives me a strange error when I try to locate the wand even when I use the same code as yesterday I'll post a picture of the error below any help would be much appreciated thanks

Was the closing an accident? I'm not sure what the issue is, but I was planning on digging out my wand to try to recreate it
