I might be doing it wrong, but I cannot get the #build command to work. I have the file in the correct folder I believe, but it gives me this error in the Launcher log.

"[Info: 2019-12-15 02:59:42.0783597: GameCallbacks.cpp(142)] Game/rd (main) Info [STDERR]: baritone.api.command.exception.CommandUnhandledException: java.lang.UnsupportedOperationException: 1.13 be like: numeric IDs btfo"

I am fairly certain the files are in the right place, and I have used correct spellings. What have I done wrong here?

Make sure your schematic is 1.12
