Custom GP tool (script) setting parameters correctly before publishing

EmmaButzler — Sat, 22 Mar 2025 01:26:12 GMT

I apologize, I don't really know how to ask my question well....I created a custom GP tool that allows user to trace a route over an existing transportation route, then the end lines split the existing route, a buffer is created to then select the features that are within the route chosen and copy the features.

Basically, I want the user to choose any section of a route (routes are typically random lines segments) and it will copy that section. The tool run successfully in ArcGIS when things were hardcoded. used arcpy.GetParameterAsText(#) for spots that had hard code but I don't necessarily want my user to be naming things that are intermediate steps. I attached my code and here is how i set up my parameters.

When I publish my GP tool on my ArcServer and I add my custom tool to an analysis widget, I have the necessary data within the web map to run the tool. i get this error.

Overall, I only want my input to be a route that the user selects and everything else to be coded so it shows up with the name I choose so that it is clear for the next steps. I am not sure how to get a feature class to show up as an output without marking it as a parameter within the arcGIS tool. Any tips on how to set my parameters so that it will run within my web tool?

Hi,

As you are saying basically the tool is copying the route section user selected, when the output should be a feature class type, right?
But why you need to "get a feature class to show up as an output without marking it as a parameter within the arcGIS tool."?
