I copied all the blocks following the tutorial, but the app keeps crashing when i try and run it in the companion app? It will flip one maybe two cards then closes and closes connection too

Expected a native object. Irritants: (0)
Note: You will not see another error reported for 5 seconds.

This is what my code says and I'm not sure what it means. I've checked the code with the video too. Could someone please tell me what this means? Thank you.

tq for the sharing! I love it. BTW, if you want it to fullscreen, set height percent to 28 and width percent to 50. :)
