Smart Edit Error when open pages

Hi All,

Recently I have configured a new store and smartedit is opening fine, but when I select any page, the loading endless animations is being presented, and the following messages are being displayed in browser console:

Missing SmartEdit attributes on body element of the storefront - SmartEdit will resume once the attributes are added

Do anyone has experienced this error? How do I can fix it?

Thank you, in advance,

Best Regards,

Rodrigo
