Amazfit Watch faces

Hello and good morning to forum. Can anyone who has knowledge help and tell me what is wrong and the converted watchfaces i attach why all have black screen. Other watchfaces i convert works fine. Some others like this watchface have black screen after convert to GTR3 Pro. Do I need to do some setting in the editor on some watchfaces that after the conversion have a black screen? If it's possible please fix the error. Thank you.

If watchface make by use custom script , it can not use Sasha's editor to unpack .
after unpack that watchface with Sasha's editor , you can found only image resource. But program will not make .json

if who want to edit you must to know about how to code in the index.js and remove custom script in index.js that in the watchface .zip before use Sasha's editor unpack , and add custom script again after packed.

Τhank you very much for the information, from what I understand someone without knowledge like me is difficult or impossible to make it. Shame. Thank you.
