I'm getting an error when trying to run a custom step based on JTXDesktopSteps.LaunchGPTool. The first time I run the GP tool it does as expected, but the second time (until I restart ArcMap), I get the following error:

I don't know what this means.

Any help is really appreciated.

Hi Meggie.

Thanks for the reply. Yes, it require inputs to run, and I do fill that out. But it can run the first time, so the inputs doesn't seem to be invalid. It's the second time I run it I get the error.

Hi Carsten,

Does the GP require any inputs to be entered while running Launch GP step? Based on the error you saw, the input parameter you entered seemed to be invalid.

Thanks,

Meggie
