Hello,
I am creating a plugin for Dynamics 365 using c#, however, I am facing issues using InArgument<OptionSetValue> I am referencing the correct entity and the correct field. 
I get the value of the OptionSet as follows 
However, when I try to trigger any method on the OptionSetOne
I always trigger an error in Dynamics 365.
This is my form data and the UI of the Dynamics 365 obviously recognizes that there is a OptionSet.
