Hi @Junaid11 ,

 

As far as I am concerned,property has to be defined as nillable in the schema or else it will throw an exception.

If it is an array, it must be an array of strings, where each string is the name of one of the basic types, and each element is unique. In this case, the JSON snippet is valid if it matches any of the given types.

https://json-schema.org/understanding-json-schema/reference/type.html 

Please check the [] and null property in your json file.
