When requesting data for a security through its ISIN over the DSS REST API, I find out very late that actually that security is "not in the dictionary". This happens only through a bad error that I trap when trying to get the row.DynamicProperties.Item(<field name>). It suddenly tells me that the row object is not defined anymore !
But the real reason can be found by using the exception's InnerException.GetBaseException.Message, which says: "The given key was not present in the dictionary."
Isn't there a "faster" way for me to find out about that, right after getting the result of my request ? A kind of status of the request's result ?
