ERROR 000816: The tool is not valid.

SergioFernandez1 — Fri, 13 May 2016 20:42:14 GMT

Hi, I'm trying to run a geoprocessing tool that I published and just get these errors:

ERROR 000816: The tool is not valid.

Error executing tool.

The process runs fine in ArcMap with a couple of layers loaded. These layers' mxd is also published.

I wonder if the published geoprocessing tool doesn't find the required layers in the published service because I didn't reference them in any place.

Where I can set this reference?

Or can you give me any guidance regarding this error?
Thanks!

yes the most unanswered error on GeoNet as you have probably noted, with one vague reference to paths to the tool or its requirements not being found. You are in good hands since most of the errors arose from similar people trying to publish something that worked in ArcMap Good luck Published GeoProcessing Task not working on ArcGIS Server. Is this a Python script issue?

I still have this same problem. The paths are well referenced and accesible and haven't find any other reason for this error. Any other thing to check? Thanks

Tech support is probably going to want to have a look...I presume you have filed a request. they will need your data and processing steps if applicable, to test

Thanks Dan.

I'm working in a test environment and I do not have access to request a support case.

The issue should be: The geoprocessing tool/ service is not compatible with the ArcGIS version you are using. It is because the service is not supported in that particular ArcGIS desktop. Try upgrading your ArcGIS version, it should work.

Good luck.

Esri Accounts the support link...

Yes. There's where I get the "You do not have access to request a support case" message

So how do you manage or get access to your software? Do you belong to an organization where someone else is the person responsible for contacting esri support? Are you with an educational institution where this would definitely be the case? If you don't manage your own software (ie, you bought it), then someone else manages the account... they are the person you needto contact

I have the exact same issue after "exporting as a python snippet" the results of a metadata conversion tool. The GUI tool works well and outputs a valid result (metadata XML file), but the python snippet only comes out with the error code 00816.

In other words, the same on-the-shelf tool works when called from the GUI, and not from Python (using the same arguments). This is not a case of upgrading versions. Or downgrading - I observe the issue in ArcGIS 10.5.1, but the process was working in previous versions (10.0, 10.4 proved OK here and used regularly).

There seems to be a disconnexion between the GUI and arcpy - can this be? Has anyone observed the same?

I found a workaround on GIS Stackexchange. There is an interaction between versions of Python (32 bits or 64 bits) and arcpy tools. My simplistic python snippet is working if I call it with 32-bits python, and not with 64-bits python.

I am having this same issue. The tool runs fine in ArcCatalog (10.7), and runs from from PowerShell, but when I run it via the Task Scheduler (in PowerShell or CMD) it fails with the 816 error. The python script is actually being called from a Node app, but this works fine when tested directly in PowerShell from within VS Code. Any thoughts would be helpful. I am running python from "C:/Python27/ArcGIS10.7/python.exe". All I want to do is dump SDE to a FGDB daily, unattended, but this task is proving extremely difficult.

Figured it out. I was using a custom tool and after moving that tool to the same location as the model toolbox and importing the custom toolbox into the python script it worked.

I know this is very old, but for the record, I started getting this error when I tried to import a python class that I created and placed in the same directory at the pyt file.

from session_logger import SessionLogger

I can import modules OK from that directory but evidently I can't import class files.
