Error message

填写抖音草稿表单失败: caption-editor-missing

What it means

When a caption is provided, fillDraftComposer locates a '[contenteditable="true"]' element to insert the caption text via document.execCommand('insertText'). If no contenteditable editor exists on the composer page it throws this CommandExecutionError with reason 'caption-editor-missing'.

Solutions

1. Retry the command — the editor may mount slightly later than the title fill
2. Check the composer DOM for the caption editor's new selector and update '[contenteditable="true"]' in clis/douyin/draft.js:97
3. Omit --caption temporarily if the caption is optional for your workflow, then add it manually in creator center

Example fix

// before
const editor = document.querySelector('[contenteditable="true"]');
// after: wait/poll for lazy-mounted editor
const editor = document.querySelector('[contenteditable="true"]')
  || document.querySelector('.editor-content[contenteditable]');

try {
  await opencli.douyin.draft({ video, title, caption });
} catch (e) {
  if (e.message.includes('caption-editor-missing')) {
    // retry, or save draft without caption and add it manually
  }
}

When it happens

Trigger: Passing a non-empty --caption while the composer page has no visible contenteditable editor — Douyin redesigned the caption box, the editor is inside an iframe, or the editor only mounts after the title is filled and a small delay passed.

Common situations: Douyin switched from contenteditable to a different editor component; caption field lazy-rendered; a modal overlay intercepting focus so the editor node is not present at query time.
