Right now `DateTime(null)` means no partitions were there, `500` means some other error(e.g. cube absent etc) `DateTime(value)` means partitions were there and latest is the `value`. If we add `NonNull`, server throws `500` in both the cases: no partition and cube absent. Ideal solution would be to have custom error codes and never throw 500. Creating https://issues.apache.org/jira/browse/LENS-488 for this. The current distinction seems good enough to me. - Rajat ----------------------------------------------------------- This is an automatically generated e-mail.
