Unexpected WeChat Channels probe: ${JSON.stringify(probe)}

Error message

Unexpected WeChat Channels probe: ${JSON.stringify(probe)}

What it means

Final sanity check: if the probe result is none of the known kinds ('auth'/'http'/'exception') and lacks ok:true, the tool throws this CommandExecutionError embedding the raw probe object. This guards against unexpected probe shapes — including probe being null/undefined when page.evaluate returned nothing.

Solutions

1. Inspect the JSON in the message to see what the probe actually returned.
2. Retry — a torn-down evaluation context is often transient.
3. Ensure the platform page stays open and fully loaded during verification (avoid navigating away).
4. Update the CLI — the probe schema may have changed server-side and needs a newer probe script.
5. If it reproduces, capture the page state (URL, cookies) and file a bug with the probe JSON.

Example fix

// before
const probe = await page.evaluate(`(async () => { ... })()`); // may return undefined
// after
const probe = await page.evaluate(`(async () => { ... })()`);
if (!probe) throw new CommandExecutionError('Probe did not return; page may have navigated — retry');

// Guard the raw probe yourself if calling internals:
const probe = await page.evaluate(probeScript);
if (probe == null) throw new Error('Probe returned nothing — page navigated or closed; retry');

function isKnownProbe(p) { return p != null && typeof p === 'object' && ('ok' in p || ['auth','http','exception'].includes(p.kind)); }

try {
  const identity = await verifyWechatChannelsIdentity(page);
} catch (e) {
  if (/Unexpected WeChat Channels probe/.test(e.message)) {
    console.error('Raw probe:', e.message); // capture for bug report
    return verifyWechatChannelsIdentity(page); // single retry for torn-down contexts
  }
  throw e;
}

When it happens

Trigger: page.evaluate returns null/undefined (page closed or navigated before the async IIFE resolved); a future/unknown probe response shape; the evaluate serialization dropped the result object.

Common situations: Slow page where the async probe hadn't resolved and the context tore down; automation framework returning undefined for pending promises; version mismatch between the probe script and expected result schema.
