Validation error (Not supporting anyOf property)

[anshul-031]

We are trying to use the new Validator().validate() method of jsonSchema Library, But we are not getting accurate result in case schema parameter contains anyOf property.

For example: We have a payload which we are trying to validate against a schema having anyOf property. Our payload is satisfying one of the pattern of "anyOf" but still getting the validation error. Below are the details of payload, schema & validationResult received. Please look at this issue at earliest, Quite urgent for us.

payload =
{ "_ItemAmount": [{ "AmountInTransactionCurrency": 20 }] }
