envelope.false_schema

Refused 400 schema

A field SOM 1.0 explicitly forbids, in the SOM 1.0 envelope.

Outcome	Refused, 400
Source	schema: The SOM 1.0 JSON Schema says no. The message is not valid SOM 1.0.
Checked at	SOM envelope, version and payload (see the order of checks)

What it means

The message breaks the SOM 1.0 envelope. A field SOM 1.0 explicitly forbids. Typical cause: signature, source (now originating_system), ai_enrichments.

How to fix it

Remove the field; use its SOM 1.0 replacement where there is one. path in the violation points at the field.
