Failed to fetch quote for ${symbol}

Error message

Failed to fetch quote for ${symbol}

What it means

Fallback CommandExecutionError in `clis/barchart/quote.js:114` when the quote fetch produced no data or returned an `error` field but that error string was empty/unavailable. It wraps the inner-script failure ('Could not fetch quote for ...') or the generic message so the CLI surfaces a consistent quote-fetch error.

Solutions

1. Read the underlying `error` message included in the thrown CommandExecutionError for the root cause.
2. Check network reachability of barchart.com (proxy/VPN/DNS).
3. Verify the symbol is valid and listed.
4. Retry with backoff; Barchart may be rate-limiting or blocking the client.

Example fix

// before
throw new CommandExecutionError(data?.error || `Failed to fetch quote for ${symbol}`);
// after
const msg = data?.error || `Failed to fetch quote for ${symbol}`;
console.error(msg); // includes inner 'Could not fetch quote for X: <cause>'
throw new CommandExecutionError(msg);

function assertSymbol(s){ if (!/^[A-Z0-9.\-]{1,10}$/.test(s)) throw new Error(`invalid symbol: ${s}`); }
// also: const reachable = await fetch('https://barchart.com').then(r=>r.ok).catch(()=>false);

const isQuotePayload = (d) => !!d && typeof d === 'object' && !d.error && (typeof d.row === 'object' || 'symbol' in (d.row||{}));

try {
  const quote = await cli.run(['barchart','quote', symbol]);
} catch (e) {
  if (e.message.startsWith('Failed to fetch quote')) {
    console.error(e.message); // includes inner cause
    // check connectivity, retry with backoff
  }
}

When it happens

Trigger: `barchart quote SYMBOL` where the in-page fetch throws (network error, timeout), Barchart blocks the request, or the script returns null/undefined data.

Common situations: Network outage or DNS failure to barchart.com, invalid/delisted symbol, rate limiting or bot detection serving an error page, expired session.
