java.lang.IllegalArgumentException: ChunkNibbleArrays should be 2048 bytes not: 0

Have you installed a 1.12 modpack? This error will usually show if you originally created your server as a 1.16 server. You can try to resolve this problem by resetting your server and starting it with Forge 1.12.

If your server is crashing with the error java.lang.IllegalArgumentException: ChunkNibbleArrays should be 2048 bytes not: 0, it means that your world is corrupt.

This error usually occurs when switching between server version (such as between 1.12.2 and 1.13.2) or server type (such as between Forge and Spigot/Vanilla). It is especially likely when downgrading to a lower version, or switching between vastly different versions.
