C# SDK GetRecord method - NullReferenceException

C# SDK GetRecord method - NullReferenceException

I'm trying to retrieve a record from Zoho given its ID. But when this record doesn't exists always I get a NullReferenceException.

Is there a way to get a freindly response instead of a NullReferenceException?
Something like status: error, message: NotExists, NotFound or something like this.

Is there other method to know if a record exists given its id?
