    Hi all,

    Just wanted to share with you some improvements we have made to logging in Python 3 scripting in the latest version of SOAR. This will hopefully help anyone writing scripts, workflows, playbooks or functions. These changes do not apply to Python 2.

    When writing scripts, you have access to log statements as described here:
    In previous versions, these log statements were only shown when interactively running a script. In v42 these log messages will also be written to the resilient-scripting.log file to help with debugging Python 3 scripts. The advantage of this is that you can view logs even when the script is run by an automated rule or playbook, and also view the logs of failed scripts.

    Here is an example of a simple log statement

    This will be output to the scripting log file as LoggerContext - Python 3 logging in SOAR v42

    Scripts that throw an error will also display logs leading up to the error

    And perhaps the most useful part of all, is that scripts in a workflow function can also be logged, meaning the results of a function can be debugged without having to add notes to an incident or any other workaround. You can also log out any of the built in object types such as incident or task to view the object data.

    We hope this helps to address some of this RFE and improve the script developer experience. Again this is only available in Python 3 scripts in v42. The log output will always be filtered by the logging level of the scripting server so by default debug level statements will be excluded.

    Hi Sean,
    Thank you for mentioning this.  Since I am quite new about SOAR and scripting, it will be of good help.

    But tell me, where is the scripting log file located?  We are using SOAR in the cloud, will we have access to this log file?

    I appreciate the work you and the team are doing to make the developer experience better. This should be a good change and I'm excited to be able to use it.

    I've been battling with an error in a condition script for 45+ minutes so I thought I'd share to see if you guys could improve the logs in this situation (or maybe point out that I'm missing something).

    I'm getting this error in the action status:

    An error occurred while processing the action acknowledgement. Additional information: Script condition from Workflow '[SOC] Suspicious Email Automation' running on Incident 'SN: EML0115619' was unable to complete because: AttributeError: 'NoneType' object has no attribute 'get'​

    and in /var/log/resilient-scripting/resilient-scripting.log I'm seeing the following:

    09:30:54.628 [qtp1611188160-83595] WARN  v=unknown - Error executing script, 'AttributeError: 'NoneType' object has no attribute 'get'' on line number 2
    com.resilient.scripting.exception.UserScriptingException: null
            at com.resilient.scripting.cpython.process.CPythonProcessCommsHandler.handleFrame(
            at com.resilient.scripting.cpython.process.CPythonProcessCommsHandler.lambda$handleMessagesFromProcess$0(
            at com.resilient.scripting.cpython.process.CPythonProcessCommsHandler$$Lambda$83/ Source)

    So I know it's a condition that has a script in it, and I can use which functions executed in the action status to gauge roughly where in the workflow this condition should be, but I'm struggling to find the condition where this error is happening. It'd be really nice if there was a way to identify exactly which condition this error was happening in from the log message.

    The file is located here: /var/log/resilient-scripting

    Hi Pierre,

    It depends what you mean by SOAR in the cloud, if you mean SaaS where you have to request access to your logs through support then this might be a difficult situation for you as you won't have access in real time. This feature might not help much in this context. Hopefully in the future we could expose this info through the UI.

    If you mean SOAR as part of Cloud Pak, Python 3 is coming soon in v1.8 and the logs will be streamed from the isc-cases-application pod in the cases-scripting-log-tailer container.

    If you are new to scripting be sure to check out some of the documentation we have put together to help with onboarding

    Hey Liam,

    Thanks for your engagement, situations like this are exactly what I hope the new logging can help with, you could just put a unique log in each condition to find out which condition had the problem.

    I would be looking for some variable that could equate to None on line 2, maybe try switch the conditions into python 2 one at a time until either the error goes away or switches to a different format that does not reference cpython (python3), then you'll know which one  has the problem.

    It would be good for us to maybe add the display name of the script in the error message, but the problem is conditions don't have names so i'm not sure what we could add there. I'll have a think about it and see if we can come up with an enhancement to help.
