GitHub releases are empty

Error message

GitHub releases are empty

What it means

After a 200 response from the GitHub releases API, fetchGitHubReleases checks that the decoded releases array is non-empty before populating the cache. If GitHub returns 200 with zero releases (empty array), the call fails with 'GitHub releases are empty' rather than proceeding with no selectable release.

Solutions

1. Retry the check later or with force=true once GitHub status (https://www.githubstatus.com) is healthy
2. Inspect https://api.github.com/repos/siyuan-note/siyuan/releases from the machine to see the raw body — if it is not a releases array, a proxy is altering the response
3. Use the stable channel instead, which does not depend on the GitHub releases API
4. Clear any interfering corporate proxy/DLP that rewrites GitHub API responses

resp, _ := http.Get(githubReleasesURL)
body, _ := io.ReadAll(resp.Body)
var arr []json.RawMessage
looksLikeArray := json.Unmarshal(body, &arr) == nil && len(arr) > 0

func nonEmptyReleases(b []byte) bool {
    var arr []*githubRelease
    return json.Unmarshal(b, &arr) == nil && len(arr) > 0
}

releases, err := fetchGitHubReleases(ctx)
if err != nil {
    if cachedGitHubReleases != nil { releases = cachedGitHubReleases } // last-known-good fallback
}

When it happens

Trigger: GET on the releases endpoint returning HTTP 200 with an empty JSON array — the repo has no published releases visible to the request, or the response body failed to unmarshal into releases leaving the slice empty.

Common situations: GitHub API outage/degraded mode returning empty payloads; a proxy or firewall stripping the response body; unexpected response shape (e.g. an error object) that SetSuccessResult cannot decode, silently yielding zero items.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
