I am receiving the following error when I deploy. How can I tell where the build error is actually taking place. I have looked at the Workflow.Targets file and that is no help in trying to track down the error. I have no idea what 'Input String' it is referencing. Any suggestions?

Error 5 The "CompileWorkflowTask" task failed unexpectedly.
System.FormatException: Input string was not in a correct format.
