# JsonUnsupportedObjectError class

Error thrown by JSON serialization if an object cannot be serialized.

The unsupportedObject field holds that object that failed to be serialized.

If an object isn't directly serializable, the serializer calls the `toJson` method on the object. If that call fails, the error will be stored in the cause field. If the call returns an object that isn't directly serializable, the cause is null.
