getCurrentCart function issue

The ‘wix-stores-backend’ getCurrentCart function appears to be returning an error (for my sites, at least) stating:
{“message”:“Read a cart is not permitted with info: Some(IdentificationInformation({AN-ID},{AN-ID},None,None,None,None,Some({AN-ID})))”,“details”:{}}
(Identifiers replaced with {AN-ID})

@andrewsmith
I have checked your site and can see that you are trying to customize the cart page by using a non-builtin button.

Please note that customizing the cart page is currently not supported.
