InvalidSchema

The schema appears to not be a valid self-describing schema.

A valid self-describing schema must contain a 'self' property with information that describes the schema, eg:

 "self": {
    "vendor": "com.vendor",
    "name": "schema_name",
    "format": "jsonschema",
    "version": "1-0-0"
  }

It's likely this property is missing or malformed.
