Hi @Hale1 ,

Have you installed the ‘Zepto Product Personalizer’ app?

This error is generated by the ‘Zepto Product Personalizer’ app, so you need to contact them for support. Refer https://apps.shopify.com/product-personalizer

Because this is the code of the app, it will be difficult for someone else to debug it for you.

Hope it helps!

@Hale1
