WebAR using unity of Universal AR


I created webAR using unity.
However, there is one problem.
When I read the QR with ipad and opened safari, it said “An error occurred running the Unity content on this page. See your browser JavaScript console for more info. The error was: ReferenceError: Can’t find variable: ZCV” An error is displayed.
I tried ipad OS 14 and 15, but both give an error.
You can open it with chrome, but you can’t open safari.
iphone can also be opened in safari. Only ipad doesn’t work. I asked other people to test it, but only ipad doesn’t work.
Help me.
