Hydraulic crashes the server (1.21.10)

Hi, the server crashes because of Hydraulic. I use Fabric, 1.21.10 with the loader version 0.17.3. Here is the exception throwed from hydraulic: ``` java.lang.NullPointerException: Cannot invoke "com.google.gson.JsonElement.getAsInt()" because the return value of "com.google.gson.JsonObject.get(String)" is null at knot//team.unnamed.creative.serialize.minecraft.metadata.PackMetaCodec.read(PackMetaCodec.java:63) at knot//team.unnamed.creative.serialize.minecraft.metadata.PackMetaCodec.read(PackMetaCodec.java:44) at knot//team.unnamed.creative.serialize.minecraft.metadata.MetadataSerializer.deserializeAndAdd(MetadataSerializer.java:95) at knot//team.unnamed.creative.serialize.minecraft.metadata.MetadataSerializer.readFromTree(MetadataSerializer.java:89) at knot//team.unnamed.creative.serialize.minecraft.MinecraftResourcePackReaderImpl.read(MinecraftResourcePackReaderImpl.java:111) at knot//org.geysermc.hydraulic.pack.PackManager.lambda$initialize$0(PackManager.java:99) at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:215) at java.base/java.util.Collections$2.tryAdvance(Collections.java:5075) at java.base/java.util.Collections$2.forEachRemaining(Collections.java:5083) at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:570) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:560) at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:636) at java.base/java.util.stream.AbstractPipeline.evaluateToArrayNode(AbstractPipeline.java:291) at java.base/java.util.stream.ReferencePipeline.toArray(ReferencePipeline.java:656) at java.base/java.util.stream.ReferencePipeline.toArray(ReferencePipeline.java:662) at java.base/java.util.stream.ReferencePipeline.toList(ReferencePipeline.java:667) at knot//org.geysermc.hydraulic.pack.PackManager.initialize(PackManager.java:100) at knot//org.geysermc.hydraulic.HydraulicImpl.onServerStarting(HydraulicImpl.java:53) at knot//net.fabricmc.fabric.api.event.lifecycle.v1.ServerLifecycleEvents.lambda$static$0(ServerLifecycleEvents.java:38) at knot//net.minecraft.server.MinecraftServer.handler$zfb000$fabric-lifecycle-events-v1$beforeSetupServer(MinecraftServer.java:3832) at knot//net.minecraft.server.MinecraftServer.method_29741(MinecraftServer.java:737) at knot//net.minecraft.server.MinecraftServer.method_29739(MinecraftServer.java:297) at java.base/java.lang.Thread.run(Thread.java:1447) ``` If you need more information, feel free to ask!
