Poor error message: "failed to parse BibLaTeX (missing number)"

[tak2hu]

Description

I tried copy pasting this bibtex from https://universe.roboflow.com/sumit-cpavr/cleaning-ghas1

@misc{cleaning-ghas1_dataset,
  title = { cleaning Dataset },
  type = { Open Source Dataset },
  author = { sumit },
  howpublished = { \url{ https://universe.roboflow.com/sumit-cpavr/cleaning-ghas1 } },
  url = { https://universe.roboflow.com/sumit-cpavr/cleaning-ghas1 },
  journal = { Roboflow Universe },
  publisher = { Roboflow },
  year = { 2025 },
  month = { nov },
  note = { visited on 2025-12-31 },
}

after typst compile main.typ it just shows the first bibtex entry without showing which key was invalid:

error: failed to parse BibLaTeX (missing number)
  ┌─ refs.bib:2:4
  │
2 │ @software{yolov8_ultralytics,
  │     ^

help: error occurred in this call of function `bibliography`
   ┌─ main.typ:35:16
   │
35 │   bibliography: bibliography("refs.bib"),
   │                 ^^^^^^^^^^^^^^^^^^^^^^^^

after changing month = { nov } to month = { 11 } it can compile, just poor error message.

This should be moved to https://github.com/typst/biblatex

#47 is relevant, but in the present case I believe it's not just an error message issue. Three letter month names are valid iirc.

I think this is a bug @laurmaedje . If I read the specification right, nov should be valid

[laurmaedje]

If I'm reading things correctly, month = nov would be correct (it also works), but month = { nov } is incorrect.

For backwards compatibility, you may also
use the following three-letter abbreviations in the month field: jan, feb, mar, apr, may,
jun, jul, aug, sep, oct, nov, dec. Note that these abbreviations are BibTeX strings
which must be given without any braces or quotes. When using them, don’t say
month={jan} or month="jan" but month=jan.
