Publishing a Python script as a geoprocessing service. Needs help.

AnthonyTwesigye1 — Sat, 11 Dec 2021 17:16:28 GMT

Hi, I am tryng to publish a relatively simple python script as a geoprocessing service. The tool works well when executed locally. It also publishes correctly, but I get the following error when the geoprocessing service executes:

I would like someone to help identify what errors I may have my code, which is attached to this message.

Also, here are the parameters of my script-

Thanks.

Anthony,

I haven't looked at your code, but I would suggest that you publish the service with the "Show Messages" parameter set to "Info", so you can get some more info about the error and find exactly where it happens.

Here is the link explaining the setting:

https://enterprise.arcgis.com/en/server/10.6/publish-services/windows/geoprocessing-service-settings-parameters.htm

Also, for your output parameter I would make "final" to be in the scratch workspace:

final = os.path.join(arcpy.env.scratchGDB, "ZonalOutput")

And to make my service return the data I set the parameter like this:

arcpy.SetParameter(1, final)

This discussion helped me resolve my geoprocessing service issues:

Good Luck!

It has been a while since I worked on this. I have been a bit engaged on different projects.

I am back on it without success.

I have enabled the info from the geoprocessing tool and used the Scratch GDB for the final output.

After republishing the tool and trying to run it, I realise that my problem is on setting environment workspace.

The current work space is ,\\xxx\arcgisserver\directories\arcgissystem\arcgisinput\test\ZonalStatisticsSolarDataAccessTestSec.GPServer\extracted\v101

The considered work spaces GDBs are ,[]

I expected to get the environment I set as \\xxx\Server Objects\Data\Raster\Solar

and then the GDBs inside this workspace

The errors are related to the tool messages on line 20 and line 28 on the attached updated script

Any idea how I can handle workspace settings.
