Orama Vitepress plugin does not work – searchbox stuck at “Loading Searchbox…”

[PierW]

Describe the bug

I am trying to integrate Orama Search inside a Vitepress project following the documentation of @orama/plugin-vitepress.
The plugin installs correctly and the project builds, but in the frontend the search UI never loads. Instead, I only see the text:

Loading Searchbox...

Clicking the search input does nothing.

To Reproduce

Create a new Vitepress project

Install the plugin

npm install @orama/plugin-vitepress

Add the plugin in .vitepress/config.js:

import { OramaPlugin } from "@orama/plugin-vitepress";

export default {
  extends: {
    vite: {
      plugins: [OramaPlugin()],
    },
  },
};

Start the dev server

Visit the site and try interacting with the searchbox

Expected behavior

The search UI should load correctly and allow searching documentation pages.

BUT

The frontend displays: Loading Searchbox...
The search input does not react when clicked.
