DOMException: Failed to read the 'localStorage' property from 'Window': In Chrome Incognito mode and running in Iframe

Question

Can anyone please help me on this issue as I'm getting this same error message on my site when I run it inside iframe of a separate domain in incognito mode only? You can access site from here.

• No issue on non-incognito mode.
• No issue without iframe as working an individual site
• No issue with those sites that don't use localStorage even running inside iframe or without iframe

Error in console -

"DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document"

Thanks
