How to debug a script based lookup?

Hello guys,

I have a lookup script, which do not runs in splunk search (doing on the search head). I will only get a:

[indexer] Script for lookup table 'lookupScript' returned error code 1. Results may be incorrect.

Well, I would expect to see any error messages somewhere inside of the logs (/opt/splunk/var/log/splunk/). But I couldn't find anything. Do you have any Idea where I can look for it?

Regards,
Peter

By default it's not recorded anywhere. What you could do is redirect your script's stderr output to a file and look there:

f = open("/path/to/some/file","w")
sys.stderr = f
