Default message: policy payload failed validation; check rule shape, action, and scope against the policy schema
HTTP status:400(client)
Problem. A policy create or update payload failed validation. Cause. The body was unparseable JSON, the rule shape did not match the policy schema, or the supplied action / scope was rejected by the policy store. Fix. Inspect the registry message for the underlying validation error and adjust the policy spec — see the policy schema reference for the expected rule envelope. HTTP 400.
