So as the title says RandomPatches is generating this error when the server is loading.

Im using a MAGMA Server (https://magmafoundation.org/) in the version "Magma Dev HEAD-44e91f6"

Server is running in Ubuntu 20.04 with JAVA:

openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1ubuntu1-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

Log ERROR:

Sorry, could I also have a debug.log?

LemADEC · Answer 4 · 2020-07-26T19:10:43.000Z

I've similar issue with SpongeForge 1.12.2-2838-7.2.3
Debug logs are here: https://gist.github.com/LemADEC/98084d018d97334880dec01b24558e53

LemADEC · Answer 5 · 2020-07-26T20:20:46.000Z

Please note there's also a crash with Piston in there, like so:

[14:58:56] [main/ERROR] [randompatches]: Failed to transform class: net.minecraft.tileentity.TileEntityPiston
java.lang.NullPointerException: null
	at org.objectweb.asm.tree.InsnList.insert(InsnList.java:377) ~[asm-debug-all-5.2.jar:5.2]
	at com.therandomlabs.randompatches.patch.TileEntityPistonPatch.patchUpdateGhostBlockFix(TileEntityPistonPatch.java:88) ~[TileEntityPistonPatch.class:?]
	at com.therandomlabs.randompatches.patch.TileEntityPistonPatch.apply(TileEntityPistonPatch.java:24) ~[TileEntityPistonPatch.class:?]
	at com.therandomlabs.randompatches.core.RPTransformer.transform(RPTransformer.java:37) [randompatches-1.12.2-1.22.0.0.jar:?]

Both issues are reproduced without SpongeForge.
Both issues are no longer reproduced at boot when removing Farseek-1.12-2.5.jar. Since that mod isn't in original context, there's probably more than meet the eyes.

TheRandomLabs · Answer 7 · 2020-09-24T01:59:52.000Z

Sorry for the late response; it seems I didn't notice that you were using a custom server. :P
@ThatOverPowered This should be fixed now.
@LemADEC I'm not sure what's causing the piston issue at the moment.
@LucidAPs Can I have a debug.log so I can figure out the NettyCompressionDecoder error?
