I have downloaded the ckeditor4 via online builder and put the file in public folder in my project. I have the cheditor4-vue integration, but want to use the local editor instead of the CDN, so I followed the documentation and put the :url-editor in the ckeditor html tag and put the path to the ckeditor.js file in editorConfig. Now when I run my application I get the error massage Uncaught SyntaxError: expected expression, got '<' in the console. Could it be that the app is serving index.html instead of the ckeditor.js that I am pointing with my path?

One more thing, if I put the path to the ckeditor.js file in the browser, I get the content of it, like I would expect the app to do.
