Model "${wanted}" not found in Trae CN model menu

Error message

Model "${wanted}" not found in Trae CN model menu

What it means

After exact and substring matching, if no model in the Trae CN menu matches the requested name, selectTraeModel throws this ArgumentError. The name normalization (lowercase, alphanumerics and dots only) still found nothing, so the model genuinely is not present in the menu.

Solutions

1. Use the exact model label shown in the Trae CN model menu
2. List available models first and pick a valid one
3. Ensure the model menu fully opens before selection (retry with a longer wait)
4. Check whether your Trae CN version offers that model at all

Example fix

// before
selectTraeModel(page, 'claude-4-sonnet')
// after
selectTraeModel(page, 'claude-3-7-sonnet') // name present in current menu

const models = await page.evaluate(listModelsScript());
if (!models.some(m => normalizeModelLabel(m.Model) === normalizeModelLabel(wanted)))
  throw new Error(`Model "${wanted}" unavailable; available: ${models.map(m=>m.Model).join(', ')}`);

const modelExists = (models, wanted) => models.some(m => normalizeModelLabel(m.Model) === normalizeModelLabel(wanted));

try { await selectTraeModel(page, name); } catch (e) { if (/not found in Trae CN model menu/.test(e.message)) { console.error('Pick one of the models listed in the Trae CN menu'); process.exitCode = 2; } else throw e; }

When it happens

Trigger: Requesting a model that does not exist in the installed Trae CN, a typo like 'gpt4o' vs 'gpt-4o' when normalization still misses, or the menu failed to load/populate before matching.

Common situations: Model names from docs of a different Trae edition (international vs CN), renamed models after a Trae update, or opening the menu too late.
