Trae CN model switch did not verify the requested model: req

Error message

Trae CN model switch did not verify the requested model: requested "${wanted}", current "${selectedLabel || 'unknown'}"

What it means

After clicking the model item, selectTraeModel re-inspects the shell and compares the now-selected model label to the requested/expected normalized keys. If the UI still shows a different (or unknown) model, it throws this CommandExecutionError, meaning the click did not result in the desired selection.

Solutions

Retry the selection; transient UI timing often succeeds on a second attempt
Increase the wait after clicking before verification
Select by a more specific/unique model name to reduce index ambiguity
Verify manually in Trae CN that the model is selectable

Example fix

// before
await page.click(TRAE_CN_MODEL_ITEM_SELECTOR, { nth: match.Index });
await page.wait(0.8);
// after
await page.click(TRAE_CN_MODEL_ITEM_SELECTOR, { nth: match.Index });
await page.wait(2.0);

Defensive patterns

Strategy: retry

Validate before calling

const info = await page.evaluate(inspectTraeShellScript());
if (info?.menuOpen) throw new SkipError('model menu still open; settle before verifying');

Type guard

const isModelVerified = (info, wanted, match) => {
  const sel = normalizeModelLabel(info?.model || '');
  return !!sel && (sel === normalizeModelLabel(match.Model) || sel === normalizeModelLabel(wanted));
};

Try / catch

try { await selectTraeModel(page, name); } catch (e) { if (e instanceof CommandExecutionError && /did not verify/.test(e.message)) { await page.wait(1.5); return selectTraeModel(page, name); } throw e; }

Prevention

Allow extra settle time after clicking before verification
Retry once on verification failure (timing is a common cause)
Prefer exact model names so the clicked row is unambiguous

When it happens

Trigger: Click landing on the wrong row after menu re-render (index drift), animation covering the item, the menu closing without selection, or the selected model label not yet updated when inspected after the 0.8s wait.

Common situations: Slow machines where 0.8s is not enough, Trae CN updates changing menu item ordering, or models whose displayed label differs from the menu label.
