iFrame issue with Zapper Unity

Hi All,
I am using Zapworks Universal SDK with Unity to build instant tracking AR experiences. Able to successfully create the effect and host on our domain with the license we had. Now the direct link works fine on Android and iOS mobile browsers.

Now when adding this link into iFrame and embedded on my other web domain and that works fine on Android Mobile web browsers. However on Safari on iphone it is through error " SyntaxError: JSON Parse error: Unrecognized token ‘<’" or sometimes

Any idea on how to resolve this ? Any help is deeply appreciated.

Hi, did you manage to find a fix for this?
