While using Panther Analysis Tool (PAT) to upload rules, I see the error "resolve body reference: could not find uploaded item."
Try updating your PAT to the latest version with the following command:
pip3 install panther_analysis_tool --upgrade
If you're still seeing this error while using the latest PAT version, please contact Panther Support with the error message output!
This could be caused by running an outdated version of PAT.
