JSON Schema Compliance Assertion

You would need a file with just the schema, something like schema.json that just defines just the schema for the assertion. Documentation here: https://support.smartbear.com/readyapi/docs/en/test-apis-with-readyapi/verifying-results/assertion-reference/compliance-assertions/json-schema-compliance-assertion.html#create-an-assertion-1009078

our swagger links have a link to the JSON file at the top - it appends openapi.json at the end.
