Exclude a not null column when using fields filter

I’m writing a query with specified fields but I’m getting the asked fields plus all not null columns. Is there any way to exclude the “not null” columns form result ? The strange thing is that I don’t use the required attribuite inside the field entity…

Please see the AutoQuery docs on returning custom fields, I.e specifying which fields to select changes which fields are queried but it does not change the Typed Response DTO schema that’s returned but you can use ?jsconfig=ExcludeDefaultValues to customize the JSON that’s returned.
