Clicked Trae CN new task via ${clicked.method}; fresh empty

Error message

Clicked Trae CN new task via ${clicked.method}; fresh empty composer was not confirmed

What it means

new.js throws a CommandExecutionError when, after clicking the new-task control, repeated probes of the page state never confirm a fresh empty composer (composerReady and turns===0). The error reports which click method was used and the observed composerReady/turns values so you can diagnose whether the click landed at all.

Solutions

Confirm the active window/tab is a Trae CN chat workspace, then retry `opencli trae-cn new`.
Check whether a recent Trae CN update changed the UI and update the click selectors/currentTaskStateScript.
Increase probe attempts/wait interval in new.js if the app is slow to reset.
Manually start a new task in Trae CN and verify the composer state script returns composerReady=true, turns=0.

Example fix

// before (new.js)
if (!state?.composerReady || state.turns !== 0) {
  throw new CommandExecutionError(`Clicked Trae CN new task via ${clicked.method}; fresh empty composer was not confirmed`, ...);
}
// after: increase probe patience
for (let i = 0; i < 20; i++) {
  await page.wait(1); // was 0.5
  state = await page.evaluate(currentTaskStateScript());
  if (state?.composerReady && state.turns === 0) break;
}

Defensive patterns

Strategy: validation

Validate before calling

// Verify the current target is a chat workspace before new
const state = await page.evaluate(currentTaskStateScript());
if (!state || typeof state.composerReady === 'undefined') {
  throw new Error('Current page is not a Trae CN chat workspace; switch targets first.');
}

Type guard

function isFreshComposerState(state) {
  return Boolean(state && typeof state === 'object' &&
    state.composerReady === true && Number.isInteger(state.turns) && state.turns === 0);
}

Try / catch

try {
  await createNewTask();
} catch (e) {
  if (e instanceof CommandExecutionError && /fresh empty composer was not confirmed/.test(e.message)) {
    console.error(e.message, e.detail); // inspect composerReady/turns
    // retry once after re-focusing the correct CDP target
    await focusChatTarget();
    return createNewTask();
  }
  throw e;
}

Prevention

Ensure the Trae CN window shows a chat workspace, not settings or another panel.
After Trae CN updates, re-verify UI selectors used by the new-task click.
Pick a stable CDP target via `opencli trae-cn targets -f json` before automating.
Allow extra settle time on slow machines.

When it happens

Trigger: Running `opencli trae-cn new` when the click method (selector/keyboard) did not create a new task: wrong window focused, page not a chat workspace, UI selectors changed after a Trae CN update, or the new task took longer than the probe loop allowed.

Common situations: Trae CN app updated and DOM selectors for the new-task button changed; user is looking at a settings or non-chat panel; slow machine where 0.5s-interval probes exhaust retries before the composer resets.
