Cisco CNAE problems with script data input

[Ida_2017]

I am trying to get the addon for CNAE to work

I have configured according to guideline, but I don’t get any data into Splunk

The splunkd.log shows me the errors:

08-04-2020 15:03:27.963 +0200 ERROR ExecProcessor - message from "python /opt/splunk/etc/apps/TA_cisco-candid/bin/collectCandid.py -candid"     main(sys.argv[1])

I have disabled SSL.

Any hint what I should look for ?

Thanks!
