Can derived outputs be optional?

Question asked by jon.morris on Nov 3, 2015

I'm working on a multi-step geoprocessing service where the outputs of some steps are inputs to others. Most of the outputs are rasters, with one or two feature classes. Some are optional, depending on the input parameters.

 

Everything runs ok in ArcGIS Desktop and I've published the services to my local ArcGIS Server. When I call the services with javascript API, the job runs ok, I get the Succeeded message, then there's an error that the data value is invalid. I think it's still trying to return a dataset, even though my script has skipped the arcpy.SetParameter line (as I am not expecting an output for these particular input settings).

 

Do I have to make my outputs Optional instead of Derived to avoid this error?

 

Here's an example of log output:

Failed.

 

You can see the input rasters are being read from the scratch workspace ok, but after the job has supposedly succeeded, the server attempts to return an optional dataset, which is not present in the gdb.

 

I've actually edited my script to save any old rubbish to the database then call arcpy.SetParameter for each of the optional outputs. Then the service completes its run without error. It would be nice if I didn't have to do such a hack though.
