What it means

The message breaks the SOM 1.0 envelope. Not an RFC 3339 date-time. Typical cause: "2026-09-24 14:00", or a time with no time zone.

Send e.g. 2026-09-24T14:00:00Z: a T, seconds and a zone (Z or an offset). path in the violation points at the field.

Branch on the rule id, never on the violation's message text. All rules: rule catalogue.
