Hello,
Access is correct.
Ok. You have 4 warnings:
1) Missing field ‘review’ (optional)
2) Missing field ‘aggregateRating’ (optional)
3) Missing field ‘brand’ (optional)
4) No global identifier provided (e.g. gtin, mpn, isbn) (optional)
You will get this warning if your product has no reviews, brands etc. Ignore unless it does have reviews, do not plan to add brands etc. It’s not an error. All it really means is you can’t get the review star rich result if you have no reviews. It is not an error with your structured data. These warnings are specifically related to getting rich results in Google search and these data are optional as you can see from the warnings.
