Publishing a GP Service with an Operational Layer

BlytheSpendlove1 — Wed, 30 May 2018 19:24:13 GMT

I am trying to publish a geoprocessing service that takes an input file from a web application, does a custom field calculation based on user defined integer inputs, and outputs a feature service that can be viewed and exported from the web application.

However, when I publish my geprocessing service and bring it into Web AppBuilder using the geoprocessing tool widget, I cannot choose the option "Add result as operational layer" and the output has the error "Can not set renderer because of unknown geometry type."

This is the REST URL for my geoprocessing service: WetlandPrioritization/WetlandPrioritizationTool_Ac (GPServer), and the screen shot below show my output parameter as having no geometry type.

Question 1) Does anybody know why I cannot see the geometry type? I am assuming this is the reason I cannot add my result as an operational layer.

Question 2) I am assuming the error above is why the tool will not run. But I also realized that I am using the python math module in my python script....Is that a problem? Do I need to download that module somehow onto my server, or can I assume the math module will work in the gp service?

My workflow for creating the Geoprocessing Service:

I created a script tool with a Feature Layer as the input, and a Feature Class as a derived output.

I then ran the tool in ArcMap (10.5) and published the geoprocessing service onto my organization's server (version 10.5). For Parameters in the Service Editor, I chose "Asynchronous" and "View results with map service," as I believe I can view the gp service results as a map service in addition to whatever my normal outputs are (such as an operational layer). I also specified maximum number of records returned by the server as 3000 because I have 2313 features in the input feature class that will be used by the tool. I then published the tool.

I have attached the source code that my web tool is running.

Thanks!

Hey Blythe

When you ran the GP tool in ArcMap, were the results added to the display? Did the output show a proper geometry symbol?

Ex.

Generally, how it behaves in ArcMap is how it'll behave as a service. I'd say the problem is definitely that the Geometry Type is null.

This isn't related to the math module, as you'd see an ImportError when running it on the Server. Can you upload the toolbox?

Hey Jonathan!

The results were added to the display in ArcMap when I ran the tool. I then changed the symbology of the results and exported the geoprocessing service. When I try and run it as a service in a web application though it doesn't work. I click the button to execute the model and the button grays out for a bit and then it goes back to normal, as if the service timed out or something.

Great to know that the math module is fine.

Attatched is the toolbox.

Thanks!

Oh whoops I was looking at the wrong thing. The output actually did not show a proper geometry symbol when I ran it in ArcMap.

Ok, that's why the service doesn't have geometry. Can you try to republish the service with the output parameter as a Feature Set, instead of a Feature Class? Theoretically, they should be the same, but that's a simple test to run. If that doesn't work, can you upload a sample input as well as parameter values I can use to try it out?

Hm, I would also use arcpy.env.scratchGDB over "%scratchworkspace%/scratch.gdb/", layerOutName:

Ex.

layerOut= os.path.join(arcpy.env.scratchGDB, layerOutName)

It's a bit cleaner and I'm not sure how well the Modelbuilder approach of %<output>% works in python script tools.

Alright so it didn't work as a Feature Set, but then when I specified the output in the script tool parameters as Feature Layer, and also specified that the derived output was obtained from the output layer, it worked! It showed the proper geometry symbol in ArcMap when I ran it and when I used the geoprocessing service in Web AppBuilder the tool did not have any issues with the geometry type either! It let me change the default symbology and everything. It still doesn't work haha, but the geometry issue is solved now

This is how I edited the output parameters:

Oh thank you! That might be the thing that is still causing me problems when I try and run the tool. I'll change that now and see if that works. (Right now I am getting a generic "Unable to complete operation" error).

Turn on Info messages and then monitor the traffic using Fiddler or the dev tools in your browser to see the job status:

You can also run it at REST but need the correct syntax for the input feature layer, which you can set as a default through the service editor:

print statements also won't return in script tools or GP services, so you may want to review lines 58-63, (at least in the original script):

elif result:
        print(type(result))‍‍
else:
        # Raise custom exception
        raise WrongInputs(result)‍‍‍‍‍

If result is not equal to 1.0, then should it fail? You don't need the elif result line if anything other than 1.0 should fail.

Thank you! And yes, if the result is not equal to 1.0 it should fail.

Not sure if you've addressed this yet, but your 6th parameter, (Output Layer Name), is set as a Feature Class, which may cause issues if you're using that value to create the path to the output.

Oh yeah, I did change that. I changed it to string. Thanks!

If you're executing this primarily through a WAB Dev edition app, you can also modify the message settings of the GP widget (during the testing phase) so you can see all the messages after the script runs (https://community.esri.com/thread/200639-wab-how-do-i-customize-output-messages-in-gp-widget-output-tab )

Thank you! That is helpful to know!
