Thanks for the help on this, definitely a good explanation for beginners trying to figure out hosting and modding, which I am. One thing though, the above commands work with certain items and materials, but I couldn't get it to give me any blocks or specifically beds. Tried for an hour or so guessing different attributes it may have, but never got it working. A friend and I were trying to test if the bed spawn mod worked on his server which he's hosting on a kubernetes cluster, but we couldn't figure out how to spawn one in to test. We just decided to run the server with the mods and make one from scratch, which doesn't take long, but this still begs the question how to spawn in blocks and other items with /giveitem dev commands. Hopefully you see this and solve my mystery. Thanks again!
