Geeting error in Splunk Appinspect :- Check that python version is python3 for executables in restmap.conf.

[sacumen]

While running AppInspect(version 2.1.0) against splunk addon getting an error "check_rest_handler_python_executable_exists - Check that python version is python3 for executables in restmap.conf." even I updated it to python3 but still the same error is there however if I am running with old appinspect(version 1.7) it passes splunk app-inspect.

Kindly let me know what I am missing here.

Thanks.

following the solution on this post I added the puython3 conf to restmap:

[admin_external:TA_nozomi_networks_add_on_account]
handlertype = python
python.version=python3
handlerfile = check_rest_endpoints.py
handleractions = edit, list, remove, create

But I'm still having the validation error 😞

Someone can help me?

Thanks!

This check was newly added as part of appinspect 2.1.0 in order to encourage Python3 adoption over Python2.7

Please include the python.version = python3 in the restmap.conf stanzas.

Example:

[admin_external:my_settings]
handlertype = python
handlerfile = file.py
handleractions = edit, list
python.version = python3

If you still encounter issues, please post your restmap.conf file.

Thanks a lot. It worked for me!!

I had also implemented the same and it started working.
Thanks.

I am also getting this issue running splunk 8.04 and add-on builder v3.0.1. I'm developing an add-on that makes some very simple REST API calls (add-on works fine).

I also changed the global python.version to be python3 in server.conf as well as adding python.version=python3 entries in each of the scripts defined in restmap.conf. I still get the error when running "validate" in the add-on builder (which runs appinspect).

I tested another REST based add-on that previously passed appinspect. It now fails with the same error. This add-on is already on splunkbase and is showing the "AppInspect passed" badge:

https://splunkbase.splunk.com/app/4976/

Looking at this page, the entry near the top suggests appInspect was updated 28th April

https://dev.splunk.com/enterprise/docs/releaseapps/appinspect/appinspectreferencetopics/splunkappins...

I'm going to email a link to this ticket to the app inspect email address to raise awareness. You should add the "appinspect" tag to this ticket if you can.

[stuartidelta01]

restmap.conf - note that I have modified this to add the python.version lines, the add-on builder does not include this by default. Both setups return the error as per original post

(Update - this now works OK for me)

  [admin:TA_add_on_for_carbon_intensity]
    match = /
    members = TA_add_on_for_carbon_intensity_settings, TA_add_on_for_carbon_intensity_generation, TA_add_on_for_carbon_intensity_regional, TA_add_on_for_carbon_intensity_intensity

Can you please share the error message as well.

[stuartidelta01]

Just managed to get the add-on through the app inspect phase. I had trouble connecting to the app inspect REST API for a couple of days and I think this error was confusing things. Thanks for your help - I'm will uptick your answer below as the restmap.conf above is now working OK for me.
