Troubleshooting
ELI5 Explanation
When scans fail or look wrong, troubleshooting helps you quickly find whether the issue is in packaging, scanner setup, or pipeline integration.
Technical Explanation
Common issues include scan upload failures, invalid credentials, policy timeout, stale artifacts, and false positives. A stable troubleshooting approach checks identity, network, artifact consistency, scan profile config, and policy thresholds in that order.

Hands-on Commands
Troubleshooting command checklist
veracode auth status
veracode upload --app sample --file app.zip --debug
veracode scan status --app sample
veracode findings list --app sample --status open
veracode policy check --app sample --verboseDebugging Scenarios
- Scan failures: artifact missing dependencies or unsupported packaging format.
- False positives: validate sink/source context and request mitigation review with evidence.
- Pipeline integration issues: token scope mismatch or incorrect environment variable mapping.
Warning: Retrying failed scans without changing the root cause only increases cycle time.
Interview Questions
Beginner
- What is first check when a scan fails?
- What causes authentication errors in CI?
- What is a false positive?
- Why verify artifact integrity?
- How do you confirm policy gate status?
Intermediate
- How do you troubleshoot intermittent scan timeouts?
- How do you structure evidence for false-positive review?
- How do you isolate pipeline vs scanner issues?
- How do you tune scan scope for performance?
- How do you prevent recurrence of packaging errors?
Scenario-based
- All branches fail after token rotation. What do you inspect first?
- One repository reports duplicate findings after migration. How do you clean up?
- DAST reports no auth coverage after login update. What changed?
- Critical findings disappear unexpectedly. Is that good or suspicious?
- Release blocked by suspected false positive near deadline. What is safe response?
Real-world Use Case
A platform team cut scan failure rate by standardizing build artifacts and centralizing scanner credentials in secured pipeline templates.
