Background:
I've created a small function in a notebook that uses Splunk's splunk-sdk package. The original intention was to call Splunk to execute a search/query, but for the sake of simplicity while testing this issue, the function only prints properties of the service object.
import splunklib.results as results
def get_useragent_string(hostname: str, srcports: int, destip: str, earliest:float):
return ("connected to %s" % service.info['host'])
The function works fine when I call it from a Python cell in a notebook.
get_useragent_string(hostname="XXX",srcports=49738,destip="104.16.184.241",earliest=1730235533)
The function throws this exception when I try it from a SQL statement
%sql
SELECT get_useragent_string('xxx', 49738, '104.16.184.241', 1730235533)
Any idea what is different between Python and SQL execution?
I think this is the salient part of the exception, but don't understand why this would be different in SQL vs Python.
