CreateGitHubRelease: StatusCode =

Error message

CreateGitHubRelease: StatusCode = 

What it means

CreateGitHubRelease POSTs to https://api.github.com/repos/ThreeMammals/Ocelot/releases and requires HTTP 201 Created. Any other status (401, 422, 403, etc.) throws this error. The detailed status is logged to build output before throwing.

Solutions

1. Read the logged 'CreateGitHubRelease: StatusCode = ...' value and the API response body for the precise cause.
2. 401/403: regenerate the GitHub token with correct 'repo' scope and update the CI secret.
3. 422 duplicate tag: delete the existing release/tag or skip release creation if it already exists.
4. 429/403 rate limit: retry after the rate-limit window or use a token with higher quota.
5. Check https://www.githubstatus.com if 5xx statuses appear.

Example fix

// before
var msg = "CreateGitHubRelease: StatusCode = " + result.StatusCode;
// after
var body = await result.Content.ReadAsStringAsync();
var msg = $"CreateGitHubRelease: StatusCode = {result.StatusCode}, Body = {body}";

// pre-check before creating the release
var existing = client.GetAsync("https://api.github.com/repos/ThreeMammals/Ocelot/releases/tags/" + tagName).Result;
if (existing.StatusCode == HttpStatusCode.OK) throw new Exception($"Release for tag {tagName} already exists");

try { var release = CreateGitHubRelease(...); }
catch (Exception ex) when (ex.Message.Contains("StatusCode = ")) { Error($"GitHub release creation failed: {ex.Message}"); throw; }

When it happens

Trigger: GitHub API returns non-201: invalid/expired GITHUB_TOKEN (401), missing repo scope on the token (403), validation failure like duplicate tag name or bad release body (422), or rate limiting (403/429).

Common situations: Token without 'repo' scope; tag_name already exists because the release task ran twice; rate-limited during busy CI hours; wrong API payload after Cake/addin upgrade.
