Refused 400 schemaA field the schema does not allow, 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 the schema does not allow. Typical cause: A typo, a field withdrawn before 1.0 (voice_count, transform_id), or an extension that is not namespaced com.<vendor>..
How to fix it
Remove or rename the field; put vendor data under extensions with a reverse-domain key. path in the violation points at the field.
Branch on the rule id, never on the violation's message text. All rules: rule catalogue.
