2 years ago I've also experienced this with Python 3.10.1 and tern 2.9.0.

Describe the bug A clear and concise description of what the bug is.
We run weekly Tern scans against hundreds of images on a Harbor registry (v2.1.3) with the previous Tern release v2.8.0. We upgraded to the v2.9.0 release and are experiencing Traceback split errors from /usr/local/lib/python3.9/re.py. Not all scans are failing, about 40% of the scans fail.
To Reproduce Steps to reproduce the behavior:
sudo ./docker_run.sh tern-debug "report -i %REGISTRY%/library/fluentd-syslog:v2"
Expected behavior Successful Scan
docker pull & inspect using the same image works
