Research direction

The report identifies openapi.yaml and an OAS3 validation failure involving oneOf, discriminator, and mapping, but does not include the YAML content or a complete payload. Start by obtaining a reproducible specification and tracing the schema-validation entry point; done means the same request validates or returns a useful validation error without the NullPointerException.
