[#4311] Use dimension_value json field instead of type_id
[#4311] Use dimension_value json field instead of type_id

When creating disaggregation in nested data, the serializer ignores the
type_id field, even if we are using it for generating the response. This
commit manually adds the dimension_value json field to the data, if
type_id is present in it.
