Incomplete data in Other Shopware Store Versions (6.0, 6.1, 6.2, .6.3)

I am encountering an issue when calling for different versions of Shopware Stores (6.0, 6.1, 6.2, .6.3) the endpoint http://storename/api/v3/_info/open-api-schema.json (for 6.3 and 6.2) and http://storename/api/v2/_info/open-api-schema.json , for the product entity, the field “required” which contains the required field for the product entity are not present, yet in http://storename/api/v1/_info/open-api-schema.json (for both versions 6.0 and 6.1) are present. The field fields are present only on Shopware 6.0 and 6.1
