At first, I put a sponge in the forge and used it I'm trying to change to Cat Server, but it shows up in the console below

is 1.12.2

[21:08:33] [Server thread/INFO]: Injecting existing registry data into this server instance [21:08:33] [Server thread/INFO]: Registry EntityEntry: Found a missing id from the world sponge:human [21:08:33] [Server thread/ERROR]: Unidentified mapping from registry minecraft:entities [21:08:33] [Server thread/ERROR]: sponge:human: 75 [21:08:33] [Server thread/WARN]: Forge Mod Loader detected missing registry entries. There are 1 missing entries in this save. If you continue the missing entries will get removed. A world backup will be automatically created in your saves directory. Missing minecraft:entities: sponge:human

If you move the sponge mod Bukkit map to the forge mod Bukkit map, (missing minecraft entities sponge human) If you ignore it and run it I was wearing protective 4444 armor, but I was killed by a magma slime in 2-3 hits. The expectation is that the user entity is either removed or not recognized, so it ignores the armor. Can you please help?
