Network failure fetching ${label}: ${e?.message ?? e}

Error message

Network failure fetching ${label}: ${e?.message ?? e}

What it means

openreviewFetch wraps all HTTP access to the OpenReview API and converts a fetch rejection (DNS failure, connection refused, TLS error, timeout) into a CommandExecutionError with a remediation hint. This guarantees network problems are never mistaken for empty results. The message includes the underlying error text for diagnosis.

Solutions

1. Verify network connectivity (curl https://api2.openreview.net) and retry.
2. Check proxy/VPN settings; set HTTPS_PROXY or NODE_EXTRA_CA_CERTS if behind a corporate proxy.
3. Check OpenReview status pages for an outage.

Example fix

// before
await openreviewFetch(path, label) // throws on any network blip
// after
for (let i = 0; i < 3; i++) {
  try { return await openreviewFetch(path, label); }
  catch (e) { if (i === 2 || !/Network failure/.test(e.message)) throw e; await sleep(2 ** i * 500); }
}

import { execSync } from 'node:child_process';
try { execSync('curl -sf -m 5 https://api2.openreview.net', { stdio: 'ignore' }); } catch { console.error('OpenReview API unreachable'); process.exit(1); }

try { return await openreviewFetch(path, label); }
catch (e) {
  if (e instanceof CommandExecutionError && /Network failure/.test(e.message)) {
    await new Promise(r => setTimeout(r, 2000));
    return openreviewFetch(path, label); // one retry
  }
  throw e;
}

When it happens

Trigger: fetch() rejects while requesting ${OPENREVIEW_API}${path}: no internet, DNS outage, proxy/firewall blocking the API host, TLS interception, or the fetch timing out.

Common situations: Laptop offline or on captive-portal Wi-Fi; corporate proxy without NODE_EXTRA_CA_CERTS; VPN blocking the API host; DNS misconfiguration; OpenReview API temporarily unreachable.
