No internet — connect to download FDA drug data. (${msg})

Error message

No internet — connect to download FDA drug data. (${msg})

What it means

Thrown by fetchManifest() when the underlying network error message matches known offline signatures: ENOTFOUND, ECONNREFUSED, ECONNRESET, or 'fetch failed'. It converts the raw Node fetch failure into a user-friendly 'no internet' error before rethrowing non-network errors unchanged.

Solutions

1. Verify connectivity: ping api.fda.gov or curl -I https://api.fda.gov and restore network/DNS.
2. Check firewall/proxy rules allowing HTTPS to the FDA host; set HTTPS_PROXY if a proxy is required.
3. If running on a schedule, ensure the device is online at job time or pause the scheduler when offline.
4. Re-run the Download FDA data job once connectivity is confirmed.

Example fix

// before
throw new Error(`No internet — connect to download FDA drug data. (${msg})`)

// after — surface the original cause for diagnostics
throw new Error(`No internet — connect to download FDA drug data. (${msg})`, { cause: err })

import { lookup } from 'node:dns/promises'
async function online(host: string): Promise<boolean> {
  try { await lookup(host); return true } catch { return false }
}

catch (err) {
  if (err instanceof Error && err.message.includes('No internet')) {
    // pause scheduler, resume on 'online' event; safe to retry later
  }
  throw err
}

When it happens

Trigger: DNS resolution failure (ENOTFOUND), connection refused by firewall/proxy (ECONNREFUSED), dropped connection (ECONNRESET), or undici's generic 'fetch failed' wrapper when the machine has no route to the FDA host.

Common situations: Device offline when the scheduled download job runs, firewall blocking outbound HTTPS, misconfigured DNS, VPN dropped mid-request, air-gapped or lab environment.
