Hello, I’m getting an error message that someone already mentioned in the discussion, but there wasn’t any real solution provided. The following error shows up every time I click on the CKEditor or try to do anything with it:

CKEditorError: Failed to read the ‘cssRules’ property from ‘CSSStyleSheet’: Cannot access rules Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-Failed to read the ‘cssRules’ property from ‘CSSStyleSheet’: Cannot access rules

By quick googling of the error, it apparently has something to do with a security measure CORS (Cross Origin Resource Sharing). But my knowledge in this field is very limited, so any kind of help or insight would be greatly appreciated

I simply have the following code in a Dialog window:

VaadinCKEditor editor = new VaadinCKEditorBuilder().with(builder -> {
            builder.editorData = "<p>This is a classic editor sample.</p>";
            builder.editorType = Constants.EditorType.CLASSIC;
            builder.theme = Constants.ThemeType.DARK;
        }).createVaadinCKEditor();
        editor.setSizeFull();

Thanks for your interest on this addon.
It seems there is external css within your project, and this addon don’t have access rights to those while looping all cssRules.
No worries, I will do an upgrade on this addon to fix this issue recently. And I’ll let you know when released.

Version 2.1.0 released. Hoping the bug would be fixed.

After a quick test, it seems the bug has been fixed. Thank you very much for your fast reply and quick upgrade.

Cheers!
