Troubleshooting
A known product does not appear
The default result list shows presentations with a change in the selected period. It does not show every current product. Check that:
- the Código Nacional has six digits;
- the search has no extra restrictive terms;
- Tipo de cambio is set as intended;
- the selected Cambios, Altas, or Bajas view matches the question.
If the presentation exists but did not change between the two monthly files, it is in the search index but does not appear in a change view.
“No se pudieron cargar los datos” appears
The app could not fetch its static JSON. Reload the page first. If you are
running the repository locally, serve the built directory over HTTP; opening
site/index.html directly with a file:// URL prevents normal browser fetches.
python3 -m nomenclator_delta dist
python3 -m http.server 8000 --directory dist
Then open http://localhost:8000.
The official page shows a newer month
This can happen between an official release and the next maintained data
update. Check the app's Comparación disponible line for the months it
contains. Pages republishes the committed, validated dataset after each push to
main and on a monthly schedule. It does not collect or parse a new source
file.
A value differs from another system
Open the result's Procedencia section and note both months and SHA-256 prefixes. Compare the same field and Código Nacional in the corresponding official release. A difference may be due to release timing, a different official field, or newer source data rather than a parsing error.
When opening a GitHub issue, include the Código Nacional, compared months, field label, before and after values, and source checksum. This gives the maintainer enough information to reproduce the result.
