It is possible that, when exporting a scene, we receive errors indicating that certain information is missing. This means that there are objects in the hierarchy that used scripts that are no longer available.
Attached you'll find a script that will help you find lost scripts in the scene.
In order to use it you have to create an "Editor" folder in the project, inside any folder found in Assets, and drop the script in that new folder.
Once imported, go to the Window menu and click on the script to launch it:
This should locate in the hierarchy which objects have those missing scripts and you should be able to delete those components.
Once deleted, the scene could be republished.
