Error phantom_forward:129 Splunk_home\etc\apps\phantom\bin\scripts\phantom_forward.py called without a session token.

[chaixl]

My the Phantom app's phantom_forwarding.log generated such logs: phantom_forward:129 - C:\Program Files\Splunk\etc\apps\phantom\bin\scripts\phantom_forward.py called without a session token.

Describe my current situation：

I am able to send events to Phantom with a saved search using the Phantom add-on. However, to send events to Phantom, I have to manually press the "Send to Phantom" button, phantom can receive the event. But the Phantom add-on can't  automatically forward events to phantom,  error logs appear in the phantom_forwarding.log. How to solve the error in the phantom_forwarding.log？

I was having this same issue (except with Splunk running on Linux).  Version 4.0.35 of the Phantom App was released last week and added support for Splunk Enterprise 8.1.  Upgrading to the new version of the app resolved the problem for me.

Thanks all for your help,

When I upgrade version 4.0.35 of the Phantom App, the problem is solved.

Thanks a lot.

Could you provide more info of the set-up in splunk as well as the errors you're getting?

I am currently using Splunk Enterprise 8.1.0.1  and Phantom version 4.9.39220. 

 The error I'm getting is the Phantom add-on for Splunk can't  automatically forward events to phantom, only by manually pressing the "Send to Phantom" button, phantom can receive one event. I checked phantom_forwarding.log， Found many errors in the log, as shown below：

2020-12-07 15:36:52,372 ERROR	phantom_forward:129 - C:\Program Files\Splunk\etc\apps\phantom\bin\scripts\phantom_forward.py called without a session token.

 I tested and found when a new event is generated for the saved search that has been forwarded in the phantom add-on configuration, there will be an error like the one above in the phantom_forwarding.log 

Here is my set-up in splunk:

In Splunk Web, I have successfully configured the Phantom Server in the App, and applied the Splunk Enterprise instance IP under the "allowed ips" in Phantom.
