Midjourney composer submit control was not found

Error message

Midjourney composer submit control was not found

What it means

CommandExecutionError from clickComposerSubmit. The helper evaluates page DOM to mark the composer's submit button with data-opencli-composer-submit; the heuristic (text-based submit button or first of >=2 following buttons) must find an enabled button, otherwise it fails closed rather than risking clicking the wrong control (e.g. Settings).

Solutions

1. Wait for the composer to fully render before calling clickComposerSubmit (page.wait or wait for composer selector)
2. Verify the submit button is enabled (not disabled) and visible in the browser
3. Update the CLI to a version matching the current Midjourney DOM
4. Take a DOM snapshot of the composer area and adjust the [data-opencli-composer-submit] marking logic/labels

Example fix

// before
await clickComposerSubmit(page);
// after
await page.wait(1.5); // let composer hydrate
if (!(await page.$('[data-opencli-composer-submit]'))) {
  console.warn('Composer submit not present yet');
}
await clickComposerSubmit(page);

await page.waitForSelector('[data-opencli-composer-submit], .composer', { timeout: 10000 }).catch(() => null);

try {
  await clickComposerSubmit(page);
} catch (e) {
  if (String(e.message).includes('composer submit control')) {
    await page.wait(2);
    await clickComposerSubmit(page); // retry after render
  } else throw e;
}

When it happens

Trigger: Calling clickComposerSubmit(page) when the Midjourney web composer is not rendered, is collapsed, the submit button is disabled, or the DOM markup changed so the text/heuristic selectors match nothing.

Common situations: Running the click before the page/imagining session has finished loading; Midjourney UI redesign changing button labels/structure; being on a page without an imagine composer (e.g. a video or settings view).
