message_type.unknown

Refused 400 policy

No SOM 1.0 schema for this message_type, on a bus that refuses those.

Outcome	Refused, 400
Source	policy: This bus's operational rules (identity, grants, size, idempotency, story ownership). Not a verdict of the SOM standard.
Checked at	SOM envelope, version and payload (see the order of checks)

What it means

A bus can be configured to refuse message types that SOM 1.0 has no schema for. The hosted environments accept them instead, with payload.unvalidated.

How to fix it

Use a SOM 1.0 message type, or publish to an environment that accepts unknown types.
