error: no milestone found with name '%s'

Error message

error: no milestone found with name '%s'

What it means

`milestoneValueToNumber` resolves a milestone given by name to its number by case-insensitively comparing against all milestones fetched for the repository. If no milestone title matches the provided value, it returns this error. The lookup is exact-modulo-case: partial names or numbers-as-strings do not match.

Solutions

1. List milestones (`gh milestone list` or web UI) and use the exact title, e.g. `--milestone "v1.0"`.
2. Check you are in the intended repository — milestone lookup is repo-scoped.
3. If the milestone was renamed/deleted, update scripts to the current title or recreate it.

Example fix

// before
gh issue list --milestone "v1"      // no milestone titled v1
// after
gh issue list --milestone "v1.0"    // exact existing title

milestones := fetchMilestones(repo)
var match *github.Milestone
for _, m := range milestones {
    if strings.EqualFold(m.Title, wanted) {
        match = &m
        break
    }
}
if match == nil {
    fmt.Fprintf(os.Stderr, "milestone %q not found; available:\n", wanted)
    for _, m := range milestones {
        fmt.Println(" -", m.Title)
    }
    os.Exit(2)
}

When it happens

Trigger: Passing `--milestone <name>` to `gh issue` (listIssues), `setMilestoneFromArgs`, or via `pullRequest` where `<name>` matches no milestone title in the repo (case-insensitive).

Common situations: Typos or partial names (`v1` vs `v1.0`); the milestone was deleted or renamed; targeting the wrong repository which has different milestones; passing a milestone number where a title is expected.
