ckeditor5 npm error Warning export 'filename' was not found

I'm doing the ckeditor5 build.

ckeditor5 plugin duplicate error occurred I was revising it by referring to the address belowten thousand You are getting stuck in a new error. https://github.com/Technologie-Visao/ckeditor5-video/issues/12

Things I've tried.

I matched the version (33.0.0) of the @ckeditor packages recorded in the main package.json and ckeditor5-video.
The issue related to ckeditor5-video/src/video/utils.js in the above error picture appears because there are no utils in @ckeditor, so additionally, Successfully installed npm install --save @ckeditor/ckeditor5-utils.

Any Solution ?

Solution

As a result of checking, version 25 of the ckeditor5-video package was the last When I set the version of ckeditor5 to version 25 and did npm build again, it worked normally.
