Intersect Task Negative Result Error Handling

Hello,

I am working on a workflow that includes an intersect task. The workflow will be used to find the intersection of two streets.

The workflow is working as expected, however, when two streets that do not intersect are entered, I cannot find a good method for dealing with the error that is thrown. Try/Catch blocks don't seem to work, and neither does an if/then block that relies on a count of the returned results. 

The problem rests on the nature of the result of the intersect task. It is an IList, and I don't know how to query the IList to find out if there was a successful intersection. 

Does anyone have a suggestion for how to handle this type of error?

Thank a ton!
