Error message

subscribed failed: ${result.detail}

What it means

When the browser-side script throws, it returns {kind:'exception', detail}; subscribed.js rethrows it as CommandExecutionError(`subscribed failed: ${result.detail}`). This wraps any in-page JavaScript exception (failed fetch, DOM API missing, script error) that occurred while scraping the subscribed list. It is a catch-all converting page exceptions into a typed CLI error.

Solutions

  1. Read `detail` in the message to identify the underlying in-page exception.
  2. Reload reddit.com in the attached browser and retry — transient fetch/network failures are the most common cause.
  3. If detail indicates missing fields/selectors, update the CLI or its scraper to match current Reddit markup.
  4. Verify network connectivity and that the browser tab stays on reddit.com for the duration of the command.
Defensive patterns

Strategy: try-catch

Try / catch

try {
  await run(['reddit', 'subscribed']);
} catch (e) {
  if (e.message.startsWith('subscribed failed:')) {
    const detail = e.message.slice('subscribed failed:'.length);
    log.error('in-page exception', detail); // then retry or report
  } else throw e;
}

Prevention

When it happens

Trigger: page.evaluate script throws inside reddit.com: fetch rejection (network error), JSON.parse on unexpected body, DOM selectors absent because Reddit's markup changed.

Common situations: Browser offline or proxy failure during fetch; Reddit DOM/API changes breaking the injected scraper; extensions interfering with page scripts; navigation interrupted mid-evaluate.
