```bash
python3 - <<'EOF'
import json, pathlib
p = pathlib.Path("~/.config/scantpaperrc").expanduser()
d = json.loads(p.read_text())
for profile in d.get("profile", {}).values():
if isinstance(profile, dict):
profile.setdefault("frontend", {})
profile.setdefault("backend", [])
p.write_text(json.dumps(d, indent=2, sort_keys=True) + "\n")
EOF
```
Thanks it worked. I still have an error but it doesn't prevent scanning:
```
