If Splunk is running on a version that uses Python 3.8 or later, and since the SSE app relies on time.clock(), this incompatibility arises. To confirm this, the issue was tested in an environment with a Python version lower than 3.8, where it did not occur.
After discussing this behaviour with the engineering team, they confirmed the issue. They are working on a resolution, which will be included in version 3.8.1 of the Splunk Security Essentials App. The estimated release date for version 3.8.1 is the end of September 2024 or the beginning of October 2024, if everything goes as planned.
The permanent fix for this issue will be included in version 3.8.1 of the Splunk Security Essentials (SSE) App. As a temporary workaround, python version can be downgraded to 3.7.x or lower in the Splunk environment where the SSE App is installed and in use.
