Error message

no milestone

What it means

The GitHub issue-detail service renders a 'milestone' badge from the issue's `milestone` field. The Joi schema declares `milestone` as an object that is `.allow(null)` — GitHub returns null when an issue has no milestone. Since a badge cannot render a null milestone, `transform` throws `InvalidResponse` with 'no milestone'.

Solutions

1. Assign a milestone to the issue on GitHub
2. Check the issue number/repo in the badge URL
3. Choose a badge that handles milestone-less issues or guard the request

Example fix

// before
/badge/issue-milestone/user/repo/123   // issue has no milestone -> error
// after (in GitHub) assign issue 123 to milestone 'v2.0'

null

null

try {
  const milestone = await getIssueMilestone(user, repo, issueNumber)
} catch (e) {
  if (e.message === 'no milestone') return null // show 'no milestone' placeholder
  throw e
}

When it happens

Trigger: Requesting an issue-milestone badge for an issue that has no milestone assigned; API returns 200 with `milestone: null`.

Common situations: Issue was never assigned to a milestone; milestone was removed from the issue; querying the wrong issue number.
