Problem Description

Issue

Recently I created a Minecraft java edition server for a specific community. It was really bare bones, so I decided to add two mods to the server (tpa and death chest). I couldn’t start the server, so I screenshot the console message and used kodee to help - my returned response was that the tpa mod couldn’t work with the server because the mod wasn’t compatible with the version of minecraft for this server. I deleted it, and then checked the console to get a completely different message. The assistant said that it’s a problem with the “world save”. I’m not sure if that’s right, but this is the error I got:

Caused by: java.lang.IllegalStateException: No key dimensions in MapLike[{}]; No key seed in MapLike[{}]
	at SECURE-BOOTSTRAP/datafixerupper@8.0.16/com.mojang.serialization.DataResult$Error.getOrThrow(DataResult.java:287) ~[datafixerupper-8.0.16.jar!/:?] {}

What should I do?

Reproduction Steps

  • Set server type to forge
  • Added mods folder in the Minecraft folder in the file manager
  • Uploaded two modifications to the folder
  • Deleted one of them (wrong version
