After clicking insert/edit embedded media in the editor (wysiwyg) in magento admin, appears an error in my console. Indeed I can upload a video, but I can't insert it to my page. it says :
Uncaught TypeError: Cannot read property 'params' of undefined
FYI im using magento 2.2.9 upgraded from 2.1.7, in nginx environment, and im using
pub directory for docroot following this article https://support.hypernode.com/knowledgebase/installing-magento-2-on-hypernode/
Does anyone have any idea? Thanks in Advance.
