Issue when adding this package to a Custom ckEditor Build

[mafina]

I've used the custom builder generator:
https://ckeditor.com/ckeditor-5/online-builder/
and everything works fine up until now.

But when I try to add this package as dependency and rebuild the custom build i get this error in console log and my app doesn't work.

core.mjs:6485 ERROR Error: Uncaught (in promise): CKEditorError: ckeditor-duplicated-modules

CKEditorError: ckeditor-duplicated-modules

Any help would be appreciated.
Thanks.

I fixed this issue by copy this plugin source code src/* to custom build folder /src/lineheight/* .

And install this plugin dependencies (notice: keep them same version), then import it import LineHeight from './lineheight/lineheight.js'; ,

/* src/ckeditor.js */
// ...
import LineHeight from './lineheight/lineheight.js';
// ...
Editor.builtinPlugins = [
  // ...
  LineHeight,
  // ...
];
// ...
Editor.defaultConfig = {
  toolbar: {
    items: [
      // ...
      "lineHeight",
      // ...
    ],
  },
};
// ...

rebuild custom folder at last.
