Rest Assured Exception - invalid JSON Schema, cannot continue - jsonschema

Question

I am using TestNG along with Rest Assured.
We have json schema file. Inside the Json schema it refers to other schema using $ref attribute.
When I use matchesJsonSchemaInClasspath for Hamcrest assertion it is failing with an validation error.
The error is basically the Validator is unable to read the nested JSON schema.
Can someone help me to resolve the issue.
Error and the Json schemas are attached.

Answer 1

As the error message says, "required" should be an array of required properties and not boolean.
