Can't place minecart on rail

[EoinKanro]

Hi!
I'm getting the error when I'm trying to place a minecart on a rail

And I don't really understand if it's a problem of everythingcopper or puzzlelib / something else from the stacktrace

Can you please help?

I guess they don't work on 1.21, I'll look into it
