500 Internal Server Error out of splunklib/binding.py

[jwhughes58]

I'm seeing this error message stream when the TA-ObserveIT tries to get what I think is the configuration information.

2020-04-16 16:29:33,418 ERROR pid=28982 tid=MainThread file=base_modinput.py:log_error:307 | Traceback (most recent call last):

HTTPError: HTTP 500 Internal Server Error -- {"messages":[{"type":"ERROR","text":"Unexpected error \"<class 'splunktaucclib.rest_handler.error.RestError'>\" from python handler: \"REST Error [400]: Bad Request -- HTTP 400 Bad Request -- Invalid Events Pagination Value: TypeError(\"int() argument must be a string or a number, not 'NoneType'\",)\".  See splunkd.log for more details."}]}

I've been trying to figure out a way of printing to the app or splunkd log files the request so I can see if that makes sense. The "Invalid Events Pagination Value: TypeError" doesn't make sense to me since the inputs.conf has this in it

events_pagination = 10000

I'm out of ideas. Any thoughts on how to resolve this are appreciated.

TIA,
Joe
