KNOWLEDGE_FACT_SYSTEM_DERIVED

Fact comes from the system

HTTP status 400 Bad Request, code KNOWLEDGE_FACT_SYSTEM_DERIVED.

What it means#

The system itself holds this value (an occurrence's start, an event's or a venue's name), so it cannot be stored as a fact: a copy would go stale.

What to do#

Change the field where it lives: the occurrence, the event or the venue.

On the wire#
