[@semantic-release/github] step fails with 404 error when trying to access non-existent PR # 1

CI ログに示されている @semantic-release/github の成功ステップと、プルリクエストのコミット一覧を取得する Octokit リクエストから調査を始めます。提供されている dayjs の設定とリリースログを使って再現し、その後、plugin が解析済みのコミットから PR を選択する方法を追跡します。完了の条件は、PR が見つからない場合でも成功した release workflow が失敗せず、このケースのカバレッジがあることです。

Current behavior

success step fails with 404 error when trying to access non-existent PR # 1

Bug Report

semantic-release version: 24.2.7
@semantic-release/github version: (latest installed via npm install -g)
Node version: 22.18.0
npm version: (from GitHub Actions)
Platform: GitHub Actions (ubuntu-latest)

Description

The semantic-release process completes successfully (npm package is published, GitHub release is created), but fails at the final success step when @semantic-release/github tries to access a non-existent Pull Request # 1.

Steps to Reproduce

1. Run semantic-release on a repository with the following configuration:

   • Default semantic-release setup with @semantic-release/changelog, @semantic-release/git, and @semantic-release/github plugins
   • Repository: https://github.com/iamkun/dayjs
   • Triggered by push to master branch

2. The release process works fine until the success step

Actual Behavior

The success step fails with a 404 error when trying to access /repos/iamkun/dayjs/pulls/1/commits, even though the commits being analyzed reference PR semantic-release/semantic-release#2920 (https://github.com/iamkun/dayjs/pull/2920), not PR semantic-release/semantic-release#1.

Commit Analysis Context

The semantic-release found 8 commits since the last release, including:

• Merge pull request semantic-release/semantic-release#2920 from iamkun/dev
• Several other commits with fix/chore/test prefixes

None of the analyzed commits reference PR semantic-release/semantic-release#1, yet the plugin attempts to access it.

Questions/Concerns

1. Why is the plugin trying to access PR # 1? The commits being analyzed reference PR # 2920 (https://github.com/iamkun/dayjs/pull/2920), not PR # 1. How does the plugin determine which PRs to process?

2. Is there a configuration to prevent this? Can we configure the plugin to skip PR processing or handle missing PRs more gracefully?

Expected behavior

The success step should complete without errors, or gracefully handle non-existent PRs.
