Problem: Any value I pass to the Retrieve(argument) method returns the error below. I can't tell why.

I've tried different data types in the database I need to pull records from. I've tried to use Guids, strings, number types, etc, but none of them worked. 

I'm reaching out here in case anyone knows what may be the cause & solution. I've inserted my code below just in case.
