ArcGIS Server - Plublishing GP Service that returns error (or without default parameters)

Discussion created by DemersM on Oct 12, 2016

I want to publish a GP Service to ArcGIS Server without default input parameter. However, I also want that GP Service to return an error when no input parameter is provided.


How could I do so?


ArcGIS wont let met publish a GP Service that returns an error, and if I run it with a valid input value, it will be defined as the default value and I wont be able to remove it.
