Steps to reproduce

While I create a new Knowledge Base Pipeline ,the website shown a error:

Application error: a client-side exception has occurred while loading localhost (see the browser console for more information).

Console print:

⚡ run world-pip script http://localhost/apps
world.js:1 ⚡ run world script
/apps:1  Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.

The Reason is my workspace is lacking of some plugins (Google Drive ,Notion,Jina Reader,Firecrawl) .But there is no pop window hint me to install them.

After I install them,it no longer error again.

✔️ Expected Behavior

No Error

❌ Actual Behavior

The website shown a error instead of pop a window to hint me install required plugins.
