Doesn't output all contributors

[nikelborm]

Describe the bug

Not all commits/PRs are shown in rendered discussions.

Example of broken behavior №1

MDN GitHub org discussion #861: Thank you contributors! (Nov 25)

I'm absent there, although I've contributed in November.

Links showing my (@nikelborm) contributions:

• Commits inside mdn/content PR #41956
• The link of the same form as the one rendered by Contributors Action into MDN discussion #861:
  https://github.com/mdn/content/commits?author=nikelborm&since=2025-11-01&until=2025-11-30

Example of broken behavior №2

MDN GitHub org discussion #865: Thank you contributors! (Dec 25)

I'm absent there, although I've contributed in December.

Links showing my (@nikelborm) contributions:

• Commits inside mdn/content PR #42334
• The link of the same form as the one rendered by Contributors Action into MDN discussion #865:
  https://github.com/mdn/content/commits?author=nikelborm&since=2025-12-01&until=2025-12-31

Example of finally working behavior

MDN GitHub org discussion #867: Thank you contributors! (Jan 26)

I'm present there, and I contributed in January.

Links showing my (@nikelborm) contributions:

• Commits inside mdn/content PR #42623, Commits inside PR #42624
• The link rendered by Contributors Action into MDN discussion #867:
  https://github.com/mdn/content/commits?author=nikelborm&since=2026-01-01&until=2026-01-31

To Reproduce

Source code of MDN's GitHub Action workflow (contributors.yml), which renders these discussions

Runs of that workflow (contributors.yml)

Expected behavior

Contributions are shown for all people who have contributed in that month

Additional context

I'm not posting this because I'm upset that my contributions were not acknowledged. I'm posting this because many other people might not have been acknowledged as well.

And I understand the bug might have been fixed, hence it's finally started to render me, but it might not be, and the fact I finally appeared may just be flaky luck.

My hypotheses of these flaky situations:

1. Me, who happened to be on the last pages of pagination, and the initial script fetches only the first N
2. The script that fetches pages with data improperly handles failures, such as Rate limiting or other issues, and just silently continues without failing early or retrying.
3. Too slow indexing of PRs in the search API (seems unlikely)
4. Some problems related to the introduction of semantic search on GitHub
5. The script doesn't render contributors who have only committed one PR/commit in a month
