Config Explorer error

gcusello — Sat, 06 Jun 2020 17:55:54 GMT

Hi at all,
I tried to use the Config Explorer app on a stand-alone Splunk server (on italian Windows 10), but when opening it I have the following error message:

An error occurred!
init:
An exception of type TypeError occurred. Arguments:
('environment can only contain strings',)

and then I haven't any function or dashboard or interface.
Is there an installation or configuration action to perform to start the app?

Ciao.
Giuseppe

Hmm I think that your shell environment has a unicode string which is causing a problem with the application startup. Can you please open a "cmd" shell as the local administrator, then run this command from the SPLUNK_HOME directory:

bin\splunk cmd python

then you should get a new prompt that looks like ">>>". Now type:

import os; os.environ

and this will dumb a large bunch of text. Can you paste it here? I expect one of the strings will be prefixed with a "u" like so: u'some_value'

Cheers, Chris.

Hi @chrisyoungerjds,
Thank you for your attention.

This is the result

Thanks for providing this output. The only anomaly I can find is that there is an extra comma appearing after the RANDFILE key. I have no idea how this has entered into the OS environment but it might indicate an environment variable with no name.. I wonder if you can find it by right click "This PC" > "Properties" > Environment variables > check both boxes.

You also didn't mention what version of Splunk you are using, but some of my research indicates this might resolve if you use Python 3 - this will happen if you are using Splunk 8 and above.

All the best and let me know what you find out.
Cheers. Chris

Thanks Chris,
Probably the above error is my mistake in trying to anonymize the data I sent you!

About the version of Splunk I am using the latest 8.0.4.

In any case I am already using Python3 (I have configured server.conf as described in the documentation) even if using the command you have suggested it replies with python 2.7.
So now I forced to use Python3 and I have the following result:

But none u'some_value'.

Ciao and Thanks.

can you do the same commands as before bin\splunk cmd python and now try running this command:

import os, subprocess; env_copy = os.environ.copy(); p = subprocess.Popen(['bin\\splunk', 'btool', 'check', '--debug'], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=False, env=env_copy); o = p.communicate(); o

Thanks

Thank you for reporting this problem. I figured out what was causing the problem and I have pushed a new version to Splunkbase. OK Please download version 1.4.9 from here:

https://splunkbase.splunk.com/app/4353/

Best of luck and let me know if you have any more problems
