I would recommend to stick with the underscore character, as the dot (.) is
reserved for the nested object to be referenced in the QueryEntity. When you
mark the query entity field with "org.id", it expects that there is an field
with name "org" in this object that has nested field "id".
The field names in the query will be flattened and in this case you will end
up with 3 fields in your QueryEntity type descriptor instead of expected 5
fields: "id", "name" and "owner" which will all have the same parent object
"org" that is missing in this object (the field should be a BinaryObject
field named "org" with 3 nested fields), thus, the returned data will be
evaluated as nulls.
