plugin externalize-deps - This package is ESM only but it was tried to load by `require`

I am installing a plugin in Vite, but I run into an error message stating that the package only supports ESM, not CJS.

package.json

{"devDependencies": {"example-package": "^1","vite": "^6"  }}

vite.config.js

import { defineConfig } from "vite";import examplePlugin from "example-package"; // that's ESM import, whats a problem?export default defineConfig({  plugins: [    examplePlugin(),  ],});

✘ [ERROR] Failed to resolve "example-package". This package is ESM only but it was tried to load by require. [plugin externalize-deps]

I have installed the package correctly via npm, as the import is handled properly in the vite.config.js file. So what is the issue with ESM import?
