Suggested Fixes

  • If you do not intend to mark any property as required, remove the required property from the Schema Object as by default all properties are considered optional.
  • If you want to specify the required property, it must contain at least one entry.
  • The list of items in the required property need to be names of the properties defined inside the properties property of the Schema Object. The name of the property in the list must match exactly with the name of the schema property. Names are compared in a case-sensitive manner.
