Hi,
sorry for the lack of response here!
Anyway, that field it not mandatory as I know and I’ve also tried to upload your feed in a test catalog and I didn’t have any issue from facebook (it’s a catalog just for test, no to use for other scopes and I’m going to remove all products).
So, I’m not able to replicate the problem, can you give more info?
That’s strange. I get the error for two of my three feeds and I can’t understand why they differ. Thus I don’t know what more info to give. If the catalogue works for you, I feel like there’s something wrong with my catalogues connection to Facebook – but I don’t know what that would be.
This one has the same error: https://apporteringtillvardagochfest.se/wp-content/uploads/product-catalogs/main-product-catalog.xml
and this one hasn’t got that error: https://klickerforlaget.se/wp-content/uploads/product-catalogs/main-product-catalog.xml
I tried again that one with the error, but again I didn’t have any problem.
Try to contact Facebook Business Support https://www.facebook.com/business/help, most probably they can give you the right indication of the problem.
