Unable to get properties for the image

I have checked by my side and I can not get this error message
it seems relative to a plugin or feature enabled on your website

can't find the url to this .svg file in edit mode of the video player

no because this is only a "fake" image to show the place for a video. You must enter a video url in the options

Another thing that doesn't work properly in edit mode are the styles properties

this has been fixed in the 3.0.2 version

if you find the cause of the error message, let me know, in any case I don't think that this is a big issue
and if you add the url of your video, the image is replaced and the message should disappear
