Upgrading Vite-imagetools 5.0.8 throws an error from 4.x version

[Raul Rodriguez]

When updating vite-imagetools to 5.0.8, trying to build a qwik project fails.
Here is the error:

npm run build.types
npm run build.client
npm run build.server
npm run lint


> qwind@0.113.0 build.client
> vite build

✘ [ERROR] "vite-imagetools" resolved to an ESM file. ESM file cannot be loaded by `require`. See http://vitejs.dev/guide/troubleshooting.html#this-package-is-esm-only for more details. [plugin externalize-deps]

npm run build

Following the recommendation to rename the config file to vite.config.mts, only makes the exception be thrown later in the compilation process.
I understand that this newer version dropped support for CJS, but I don't see why the plugin externalize-app enters into play after the upgrade. It seems similar to this issue that was closed

Nvm 😞 I was missing adding package.json type: module and fix my postcss.config.mjs to ESM format
