```

Start at lib/attacks/sqlmap_scan/__init__.py line 164, where subprocess.Popen launches the sqlmap API command, and review the traceback from the reported ./zeus.py -b ... --verbose --auto -s run. Reproduce the missing-file error and determine the expected behavior when the sqlmap API executable cannot be found; done should prevent this unhandled exception or clearly report the missing dependency.
