Generate a debug bundle
Capture FOSSA CLI debug logs and send them to support to speed up troubleshooting of scan failures.

Overview
If a project scan fails through the FOSSA CLI, send a debug bundle to support@fossa.com (and/or your Customer Success team). It's the fastest way for us to diagnose the issue.
FOSSA CLI v3.13.0 and later
The bundle is a single fossa.debug.zip containing:
fossa.debug.jsonfossa.telemetry.jsonFicusdebug logs (when snippet scanning is enabled)
This single-file format simplifies collection, especially for snippet scans.
Prior to v3.13.0
Run fossa analyze with the --debug flag:
Shell
fossa analyze --debugThis writes fossa.debug.json.gz (and a fossa.telemetry.json) to the directory where the CLI ran. Send both along with your support request.
