Renaming entities not possible

Hi!
I’m trying to mass-rename a ton of entities via the “bulk import” option, so I thought i could simply use the ID of each entry to just update the name, but when i do that it gives me this weird error? And since Autodesk support is notoriously bad, i am trying my luck here if anybody has encountered and solved this problem before?
Thanks!

What did you use as the id field?
