🐞 Bug report

💻 Version of CKEditor

Classic Editor v11.0.1

📋 Steps to reproduce

1. Create a custom build of the Classic Editor.
2. Upgrade your dependencies to the latest versions available. See my package.json file : it shows what modules were updated and their current version.
3. Compile the sources and open an instance of the editor in your browser.

✅ Expected result

Everything works as previously.

❎ Actual result

The editor does not work at all, and the browser console displays :

plugincollection-plugin-name-conflict: Two plugins with the same name were loaded.
  plugin1: function contextualballoon_ContextualBalloon()
​  plugin2: function balloon_contextualballoon_ContextualBalloon()
​  pluginName: "ContextualBalloon"

CKEditorError: "model-selection-set-ranges-not-range: Selection range set to an object that is not an instance of model.Range.

I did a clean install of Node.js modules (i.e. rm -rf node_modules && npm install : no change (the error is still there).

You've got an outdated table package in https://github.com/sab-international/rich-text-editor/blob/9fcf317ca724983edc74c04421477917edb8bcf8/package.json. It's trying to load an older version of ckeditor5-ui so ckeditor5-ui gets duplicated.

We're planning to implement a webpack plugin (or recommend existing one) which will warn about such situations

But for now, make sure to run a tool like npm-check to verify whether you're using the latest packages.

Thanks @Reinmar for pointing the source of this problem. Updating the image and table packages fixed the issue 👍
