Custom Script and python 3.7 gives strange Loglevel Error

Elsurion — Fri, 17 Jul 2020 09:10:03 GMT

Hi all

I've enabled the python 3.7 Support on my installation, but now my external command won't work anymore, saying i have some syntax error, which i'm not able to find in the binary tree of my command app...

And the command works with python 2.7...

The message is:

ValueError: Unknown level: 'ERROR ; Default: WARNING'

The full log is:

07-17-2020 10:12:48.713 ERROR ScriptRunner - stderr from '/opt/splunk/bin/python3.7 /opt/splunk/etc/apps/elasticsplunk/bin/elasticsplunk.py __GETINFO__ eaddr=cluster1 index=testdrive query="state:IL or state=TN and age>22"':

Did you run the Splunk Platform Upgrade Readiness App (https://splunkbase.splunk.com/app/4698/) ? It should have identified this before you upgraded. It might have identified the change that needed to be made to support Python 3.

I've executed the readyness tool but it had only warnings and not a single blocker.
Including the splunklib which should be ready for 3....

That's why i have no clue why the logger breaks. Every other point where the syntax changed yes, but not in the logger.

Per https://docs.splunk.com/Documentation/SA-LdapSearch/3.0.2/User/UseSA-ldapsearchtotroubleshootproblems

Your app's logging.conf file has a line like this in it:
level ERROR ; Default: WARNING

And it needs to look like this:
level ERROR

@Elsurion

Came to this thread randomly for the same needs (elasticsearch Python)
I just got rid of the logging.conf and that fixes import issues in 8.2.x
