Not able to include relationships unless they are on all bundles

Problem/Motivation

Hey everyone,
I've few differents product types on my website and I wanted to get the url of my images using this link http://preprod.onbricole.fr/jsonapi/commerce_product?include=variations,...
But it came out that it's not possible to do it if my field_image doesn't exist in all my product types.
Indeed, for example it exists in default and when I'm fetching http://preprod.onbricole.fr/jsonapi/commerce_product/default?include=var... here I do get my url field of my image.
