Схема Swagger содержит несколько схем JSON, организованных в структуру API, вам необходимо обратиться к правильной части схемы Swagger, чтобы использовать схему JSON для проверки.
Проверьте код примера (https://runkit.com/embed/bwj42juwyjo4):
var Ajv = require('ajv');
var ajv = new Ajv();
var schema = {
"host": "cert",
"paths": {
"products": {
"get": {
"responses": {
"401": {
"description": "Problem with the client request",
"headers": {
"x-correlator": {
"type": "string",
"format": "uuid",
"description": "Correlation id"
}
},
"schema": {
"$ref": "errors.json#/definitions/Unauthenticated"
}
}
}
}
},

ajv.addSchema(errors_schema, 'errors.json');
ajv.addSchema(schema, 'swagger.json')
var testajv = ajv.compile({ $ref: 'errors.json#/definitions/Unauthenticated' });
console.log(testajv({"code": 123, "message":"token expired"}), testajv.errors); // Fails
