Troubleshooting

Quick diagnosis paths for the most common app failures.

Failed to fetch

• Backend endpoint not reachable from current origin.
• Server process not running or wrong port/base URL.

Sync parse errors

Usually means sync returned an invalid or empty response. Re-check sync target/device ID and retry push/pull.

Data missing after refresh

• Confirm signed-in status and expected account context.
• Confirm device ID and sync target are correct.
• Use pull/push intentionally to avoid overwriting with stale data.

Import mismatch issues

Re-export plain text GCODE and re-import. Binary/packaged exports can cause metadata loss.

Debug Checklist

1. Open browser devtools network tab.
2. Reproduce issue and inspect failing requests.
3. Validate settings for endpoint and device ID.
4. Re-test with a known-good sample file.
