contract_validation_failed

A stored disclosure does not satisfy the public contract.

What it means: A row read from the warehouse failed the published schema at serve time. The API refuses to serve a row that does not match its own contract. This is a Veridion defect, not a request problem.
What to do: Quote the X-Request-ID to support@veridionmarkets.com; the row is identifiable from it.
Retry: Retry later; the request was sound. Every 503 carries Retry-After with the minimum wait.
Who changes what: Veridion. The request was sound; something on our side did not answer within its budget or failed a check. The API returned nothing rather than something partial.

Documented for version 1.3.5. The request_id in the body equals the X-Request-ID header; quote it to support@veridionmarkets.com. All problems · API page
