Hi,

The "Availability" field is not present in the "events" schema under "links"



Also, there are other fields missing under the events "registrations"
            "RegistrationTypeCode"
            "Consumed":,
            "Available":,
            "Unlimited":,
            "GroupLimited":



Have these field been removed from the schema or is it available in any other object? If they are available in any other related schema then please let us know how to fetch them in the query.
