Error message

视频文件注入失败: ${result?.error ?? 'unknown'}
截图已保存到 /tmp/wechat-channels_publish_upload_debug.png

What it means

uploadFile injects the video file into the page's file input via CDP/in-page DataTransfer. If the injected script reports ok:false, a debug screenshot is saved to /tmp/wechat-channels_publish_upload_debug.png and a CommandExecutionError is thrown with the script's error reason. This usually means the file input or upload trigger was not reachable in the wujie shadow DOM, or the in-page injection itself failed.

Solutions

  1. Inspect /tmp/wechat-channels_publish_upload_debug.png to see what the page actually rendered.
  2. Confirm you are logged into channels.weixin.qq.com in the driven Chrome instance and the create page loads.
  3. Retry once — transient render/timing issues can cause the input to be missing.
  4. If the DOM changed, update UPLOAD_TRIGGER_SELECTORS / injection script in clis/wechat-channels/publish.js to match the new markup.

Example fix

// before (stale selector)
const UPLOAD_TRIGGER_SELECTORS = ['span.add-icon.weui-icon-outlined-add'];
// after (add new markup observed in debug screenshot)
const UPLOAD_TRIGGER_SELECTORS = ['span.add-icon.weui-icon-outlined-add', '.new-upload-entry', 'div.upload-content'];

Prevention

When it happens

Trigger: Upload trigger selectors no longer match after a WeChat UI change; the creator page failed to render (login expired, wujie micro-frontend error); the in-page evaluate threw or returned an unexpected shape (result.error set by the script).

Common situations: WeChat updated the creator-center DOM; session not logged in so the create page redirected; Chrome/CDP version mismatch breaking setFileInput.
