1.20.6 Aternos Fabric Datapack

I downloaded a datapack that supposedly converts rotten flesh to leather for use on my 1.20.6 Aternos server, and for some reason it doesn't seem to work and I wanted to troubleshoot it Is there a certain way i should edit the json files or something to make it work? Datapack: https://modrinth.com/datapack/rotten-flesh-to-leather Here was the log relevant to it: [main/ERROR]: Parsing error loading recipe crafting:browndye_smelt com.google.gson.JsonParseException: Not a JSON object: "minecraft:brown_dye" at knot/com.mojang.serialization.DataResult$Error.getOrThrow(DataResult.java:275) ~[datafixerupper-7.0.14.jar:?] at knot/net.minecraft.class_1863.method_20705(class_1863.java:62) ~[server-intermediary.jar:?] at knot/net.minecraft.class_1863.method_18788(class_1863.java:35) ~[server-intermediary.jar:?] at knot/net.minecraft.class_4080.method_18790(class_4080.java:13) ~[server-intermediary.jar:?] at java.base/java.util.concurrent.CompletableFuture$UniAccept.tryFire(CompletableFuture.java:718) ~[?:?] at java.base/java.util.concurrent.CompletableFuture$Completion.run(CompletableFuture.java:482) ~[?:?] at knot/net.minecraft.class_4014.method_18365(class_4014.java:69) ~[server-intermediary.jar:?] at knot/net.minecraft.class_156.method_43498(class_156.java:993) [server-intermediary.jar:?] at knot/net.minecraft.class_156.method_43499(class_156.java:981) [server-intermediary.jar:?] at knot/net.minecraft.server.Main.main(Main.java:182) [server-intermediary.jar:?] at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:480) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.knot.Knot.launch(Knot.java:74) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotServer.main(KnotServer.java:23) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.server.FabricServerLauncher.main(FabricServerLauncher.java:69) [fabric-loader-0.16.14.jar:?] [main/ERROR]: Parsing error loading recipe crafting:leather_smoke com.google.gson.JsonParseException: Not a JSON object: "minecraft:leather" at knot/com.mojang.serialization.DataResult$Error.getOrThrow(DataResult.java:275) ~[datafixerupper-7.0.14.jar:?] at knot/net.minecraft.class_1863.method_20705(class_1863.java:62) ~[server-intermediary.jar:?] at knot/net.minecraft.class_1863.method_18788(class_1863.java:35) ~[server-intermediary.jar:?] at knot/net.minecraft.class_4080.method_18790(class_4080.java:13) ~[server-intermediary.jar:?] at java.base/java.util.concurrent.CompletableFuture$UniAccept.tryFire(CompletableFuture.java:718) ~[?:?] at java.base/java.util.concurrent.CompletableFuture$Completion.run(CompletableFuture.java:482) ~[?:?] at knot/net.minecraft.class_4014.method_18365(class_4014.java:69) ~[server-intermediary.jar:?] at knot/net.minecraft.class_156.method_43498(class_156.java:993) [server-intermediary.jar:?] at knot/net.minecraft.class_156.method_43499(class_156.java:981) [server-intermediary.jar:?] at knot/net.minecraft.server.Main.main(Main.java:182) [server-intermediary.jar:?] at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:480) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.knot.Knot.launch(Knot.java:74) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotServer.main(KnotServer.java:23) [fabric-loader-0.16.14.jar:?] at net.fabricmc.loader.impl.launch.server.FabricServerLauncher.main(FabricServerLauncher.java:69) [fabric-loader-0.16.14.jar:?]
