Errors & troubleshooting

Errors are explicit. Each maps to one fix.

• SWCAuthError — bad or blank key. Re-copy your EVAL-… key.
• SWCLicenseExpired — your 90 days are up. Convert to continue.
• SWCSessionError — you called step() before start(), or the session expired. Call start() first.
• SWCServerError — the endpoint returned a 5xx. Transient ones are auto-retried; if it persists, try again shortly.
• SWCNetworkError — the endpoint was unreachable (auto-retried first). Check connectivity / firewall.
• OutOfEnvelope — check_envelope(require_in_envelope=True) returned DECLINE. Your current method already wins here; see the envelope.
• SWCOutdatedClient — a warning, not an error: a newer runtime is available and your offline build is behind. It keeps running. Reply to your license email for the latest client, or see the changelog. Check runtime.license_info()["update_available"].
