Refused to display in a frame because "frame-ancestors 'none'"

Hello Team,

I am a new author and have uploaded a theme but getting an error “’ Refused to display ‘https://occasion-demo.myshopify.com/’ in a frame because an ancestor violates the following Content Security Policy directive: “frame-ancestors ‘none’”.

Here’s the URL “https://themeforest.net/item/occasion-sectioned-responsive-shopify-theme-for-supermarket-large-store-groceries-aliexpress/22750511

you can see in console.

I am using hoisting of system shopify.

Could you please provide any solution for this? If one of you faced earlier?

Thanks,
i-phoenix
