Error message

${pickerResult?.reason || 'Failed to open Gemini model picker for model discovery'}

What it means

This CommandExecutionError is thrown when the browser-bridge script that clicks Gemini's model picker button fails or reports not-ok. The library clicks the picker button inside gemini.google.com to enumerate selectable models; if the click throws, the bridge returns ok:false with a reason, or the envelope can't be unwrapped, this fallback message is used.

Solutions

1. Re-run the command after a page.reload() / fresh login so the model picker button is rendered before clicking
2. Increase the wait before clicking the picker (e.g. page.wait(2.0)) to let React mount the button
3. Update the picker-button selector in clis/gemini/ask.js to match the current Gemini Web DOM
4. Check `opencli gemini login` status to ensure an authenticated, non-redirected session

Example fix

// before
await page.wait(1.0);
// after
await page.wait(3.0); // let React render the picker button before clicking

const pickerRaw = await evalBridge(script);
const pickerResult = unwrapBrowserBridgeEnvelope(pickerRaw);
if (!pickerResult?.ok) { await page.wait(2.0); /* retry once before proceeding */ }

function isPickerResultOk(r) { return !!r && typeof r === 'object' && r.ok === true; }

try {
  await runAskCommand();
} catch (e) {
  if (/model picker/i.test(e.message)) { await page.reload(); await page.wait(3); /* retry */ }
  else throw e;
}

When it happens

Trigger: The injected picker.click() throws (element detached/not clickable), the bridge returns {ok:false, reason:'Failed to click Gemini model picker button'}, or pickerRaw fails unwrapBrowserBridgeEnvelope (null/non-object).

Common situations: Gemini Web UI changed so the picker button selector no longer matches; page not fully rendered before the click; slow network causing React not to mount the button; browser bridge/CDP hiccup or page navigation mid-automation.
