Solutions

1. Verify the exact modelId matches a menu entry (use the model listing command if available)
2. Re-run after the menu fully renders
3. Update the CLI for current Gemini menu DOM

Example fix

// before
opencli gemini model --set gemini-1.5-ultra
// after
opencli gemini model --set gemini-2.5-pro

const KNOWN_MODELS = ['gemini-2.5-pro','gemini-2.5-flash'];
if (!KNOWN_MODELS.includes(modelId)) {
  throw new Error(`Unknown modelId '${modelId}' — use an exact menu entry name`);
}

try {
  await selectGeminiModel(page, modelId);
} catch (err) {
  if (err.message.includes('Failed to select Gemini model')) {
    const list = await listGeminiModels(page);
    console.error(`Model '${modelId}' not found. Available: ${list.join(', ')}`);
  }
  throw err;
}

When it happens

Trigger: selectModelInMenuScript(modelId) at clis/gemini/utils.js:2739 returns ok:false or a reason — the menu item for modelId was not found or the click did not register.

Common situations: Requesting a model id/name that no longer exists in the menu; model renamed by Google; menu rendered before items hydrated; account lacks access to the requested model.
