I usually develop locally with minimum number of media items and content. Then deploy to a staging site on the same server that will host the final site. I integrate content and media on staging site. I copy the site files to production hosting environment, I set the folder permissions, and site works as expected. On an Umbraco 13.3.0 web site i followed the above routine, the site works, i can create new media items, update newly created items on production site. The problem evolves when i try to modify the media items that were added to site on staging server and copied to the production environment: When i try to change media item i get the error attached. When i check the logs i can not find a log entry related with the issue. But i noticed an error log as "An exception was thrown while deserializing the token." with the content as attached: I wondered if the media problem is related with "An exception was thrown while deserializing the token." error.
