Suggested Fixes

  • Add the subschema in the Schema Object that needs to be evaluated, using the if property.
  • If you do not want to apply a subschema conditionally remove the else property from the Schema Object.
  • Only schemas that are not valid against a subschema in if are evaluated against the else subschema. Therefore, property else alone has no effect during schema validation and works along with if to produce the overall evaluation result.
