[BUG] Validating on unsupported ChronoUnit

[jackiehanyang]

What is the bug?

As there is no named value Decade defined in the enum (ChronoUnit). This discloses the underlying framework as Java and the response is 200.

osd-name: aosa
....
{"ok":false,"error":"No enum constant java.time.temporal.ChronoUnit.DECADE"

This occurs in the period key within detectionInterval, shown below:

Also tried Forever to see what would happen but that's not supported.
