Migrator producer lookup failed: HTTP

Error message

Migrator producer lookup failed: HTTP ${response.status}

What it means

migratorPublished() polls the GitHub Actions API for cloud-migrator-artifacts workflow runs on the given commit. When any page request returns a non-OK HTTP status it throws this error with the status code embedded. It is a fail-closed API transport check.

Solutions

1. Check GH_TOKEN validity and Actions read scope, then rerun; note the script retries at the waitForCloudArtifacts poll level, so transient statuses may self-heal on the next 20s poll.
2. If HTTP 403 with x-ratelimit-remaining: 0, wait for the rate-limit window to reset or use an authenticated token.
3. Verify api.github.com is reachable and the paperclipai/paperclip repository still exists at that name.

Example fix

// before
const token = process.env.GH_TOKEN; // undefined or expired
// after
if (!process.env.GH_TOKEN) throw new Error("Set GH_TOKEN with Actions read scope before polling.");
const token = process.env.GH_TOKEN;

// preflight
const probe = await fetch("https://api.github.com/rate_limit", { headers: token ? { Authorization: `Bearer ${token}` } : {} });
if (!probe.ok) throw new Error(`GitHub API unreachable/unauthorized: HTTP ${probe.status}`);

try {
  await waitForCloudArtifacts(sha);
} catch (error) {
  if (/Migrator producer lookup failed/.test(error.message)) {
    console.error("GitHub API error — check GH_TOKEN scope and rate limits:", error.message);
    process.exitCode = 1;
  } else throw error;
}

When it happens

Trigger: The fetch to api.github.com/repos/paperclipai/paperclip/actions/workflows/cloud-migrator-artifacts.yml/runs returns 401/403/404/422/5xx — e.g. expired GH_TOKEN, rate-limited 403, renamed repository, or a GitHub outage.

Common situations: Expired or missing GitHub token in GH_TOKEN; hitting the unauthenticated 60 req/hr rate limit; GHE/proxy interference; GitHub API incident; transient network failure within the 30s AbortSignal timeout.
