Hello,

I had a custom search command working with the python2 version of splunklib. I moved now to python3 and I have this error:

I'm running Splunk 8.1.12 (under Linux) and I am using the latest SDK 1.7.2 My env python is 3.8

The script I am using is:

#!/usr/bin/env python

import sys,os

sys.path.insert(0, os.path.join(os.path.dirname(__file__), "..", "lib"))
import time
import csv
from ipaddress import ip_address, IPv4Network

from ipam_api import API as IpamApi
from splunklib.searchcommands import \
        dispatch, GeneratingCommand, Configuration, Option, validators

@Configuration()

        def generate(self):
                api = IpamApi("https://ipam3/")
                views = api.get_view_list()

                for view in views:
                        nv = view['name']
                        if nv != 'default':
                                with api.csv_export('network', network_view=nv, stream=True) as r:
                                        f = (line.decode('utf-8') for line in r.iter_lines())
                                        reader = csv.DictReader(f)
                                        prefix = reader.fieldnames[0]

                                                cidr= { 'cidr': cidr_i }

                                                dictout.update(row)
                                                dictout.update(net32)
                                                dictout.update(subnet)
                                                dictout.update(cidr)
                                                yield dictout

dispatch(IPAMExtrCommand, sys.argv, sys.stdin, sys.stdout, __name__)

Please can you help me to fix this?

thanks, Fausto

Hi @TheFausap , We have tried to reproduce issue on our end with similar environment setup (without ipam_api package), and code is working fine without any error. As we don't have access to the ipam_api package requesting you to share how we can install the package, so we can reproduce the issue.

Hi @akaila-splunk, yesterday I found the cause for this error. In my logging.conf I had an entry for "splunklib". That logging.conf was working in the past, with an older splunklib SDK. So I removed the entries below and the error disappeared.
