Failed to get user info: ${error}

Error message

Failed to get user info: ${error}

What it means

GitHubService.getUserInfo() calls GET https://api.github.com/user with the freshly obtained access token to fetch the authenticated user's profile. A non-OK response causes the raw body to be thrown as `Failed to get user info: ${error}`. Since the token was just minted by the device flow, this usually indicates a network/API problem rather than bad credentials — but a revoked or scope-less token will also fail here with 401.

Solutions

1. Inspect the embedded body for a 403 rate-limit message; if so, wait for the rate-limit window or authenticate from a different IP.
2. Re-run the device-flow authentication to obtain a fresh token, then retry.
3. Verify api.github.com is reachable (curl -i https://api.github.com/user with the token) and no proxy strips Authorization.
4. Retry later if GitHub status (githubstatus.com) reports an API incident.

Example fix

// before
if (!response.ok) {
  const error = await response.text();
  throw new Error(`Failed to get user info: ${error}`);
}
// after
if (!response.ok) {
  const error = await response.text();
  throw new Error(`Failed to get user info (HTTP ${response.status}): ${error}`);
}

}

When it happens

Trigger: GET to api.github.com/user returns non-2xx: 401 (bad/insufficiently-scoped token), 403 (rate limit exhausted for the IP), 5xx from GitHub, or an intercepted body from a proxy/portal.

Common situations: Shared IP (corporate NAT/CI) hitting GitHub's unauthenticated rate limits; a proxy stripping the Authorization header; GitHub API incident; User-Agent or X-GitHub-Api-Version rejected by an API gateway.
