Suggested Fixes​

  • Ensure that the value of type in the Schema Object is not set to a value other than object.
  • Type names are compared in a case-sensitive manner.
  • If you use the maxProperties keyword, ensure that the data instance you intend to validate can be an object.
  • If the type of the instance can vary i.e. it can be an object or some other type, consider removing the type keyword to allow any types. If you use the oneOf/anyOf constructs instead, consider moving the maxProperties to the oneOf/anyOf schema that has the type set as object.
