Hey @fxground,
I have replicated the issue in my test site so this could be a bug or a lacking feature. I’ll list this in our issue tracker so this will be queued for further investigate.
For now, please turn off the schema option because you need to write your own schema. Follow the Product Schema guide here: https://schema.org/Product or use the sample below which doesn’t have the error.
{
"@context": "https://schema.org/",
"@type": "Product",
"name": "Product Name",
"image": "https://example.com/product-image.jpg",
"description": "A short description of the product",
"sku": "12345",
"brand": {
"@type": "Brand",
"name": "Brand Name"
},
"review": {
"@type": "Review",
"reviewRating": {
"@type": "Rating",
"ratingValue": "4.5",
"bestRating": "5"
},
"author": {
"@type": "Person",
"name": "Reviewer Name"
}
}
}
