Hi @LGAtmOz, thank you for reaching out and providing detailed logs! It seems like the issue might be related to a CSRF check and a potential error with the Focalboard plugin during the import process. I recommend reviewing the “Upcoming product changes to Boards and various plugins” thread for guidance and ensuring your plugin version is up to date. If the problem persists, it may help to temporarily disable any custom plugins that could interfere with the process and try again. Let us know how it goes, and we’ll do our best to assist further!
