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


enter image description here

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.

  • have you tried inserting outside of the wysiwyg <video id="myVideo" width="100%" height="300px" autoplay="autoplay" muted="" loop="loop"> <source src="{{view url="/pub/media/movies/movie.mp4"}}" type="video/mp4" /> </video> Jul 25, 2019 at 12:31
  • hi dominic, thank you for your response. yes Ive tried to insert that directly without wysiwyg. however the error still appearing when we open / edit page in magento admin like this link . more over, we cant just insert html code for our client, he cant do that. do you have any suggestion?

  • Does seem to be more an issue with wysiwy. You could try updating the wysiwyg github.com/pavelleonidov/magento2-tinymce4 Try on dev site first. Beyond that I don't know sorry. Jul 25, 2019 at 12:54
