Minor When loading a world with a datapack, the datapack fails to load any .mcfunction file with commands in it with the following error:
[05:01:50 ERROR]: Couldn't load function at dmz:functions/_give/pickaxe/torchwood.mcfunction java.util.concurrent.CompletionException: java.lang.NullPointerException at java.util.concurrent.CompletableFuture.encodeThrowable(Unknown Source) ~[?:1.8.0_172] at java.util.concurrent.CompletableFuture.completeThrowable(Unknown Source) [?:1.8.0_172] at java.util.concurrent.CompletableFuture.uniApply(Unknown Source) [?:1.8.0_172] at java.util.concurrent.CompletableFuture$UniApply.tryFire(Unknown Source) [?:1.8.0_172] at java.util.concurrent.CompletableFuture$Completion.exec(Unknown Source) [?:1.8.0_172] at java.util.concurrent.ForkJoinTask.doExec(Unknown Source) [?:1.8.0_172] at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(Unknown Source) [?:1.8.0_172] at java.util.concurrent.ForkJoinPool.runWorker(Unknown Source) [?:1.8.0_172] at java.util.concurrent.ForkJoinWorkerThread.run(Unknown Source) [?:1.8.0_172] Caused by: java.lang.NullPointerException at net.minecraft.server.v1_13_R1.CommandListenerWrapper.hasPermission(CommandListenerWrapper.java:126) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at net.minecraft.server.v1_13_R1.CommandGive.a(SourceFile:30) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at com.mojang.brigadier.tree.CommandNode.canUse(CommandNode.java:71) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at com.mojang.brigadier.CommandDispatcher.parseNodes(CommandDispatcher.java:176) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at com.mojang.brigadier.CommandDispatcher.parse(CommandDispatcher.java:156) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at net.minecraft.server.v1_13_R1.CustomFunction.a(CustomFunction.java:48) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] at net.minecraft.server.v1_13_R1.CustomFunctionData.lambda$3(CustomFunctionData.java:169) ~[server.jar:git-Spigot-83d9d09-3e5fe3e] ... 7 more
Once in the game I can run
datapack disable "file/pack"
then enable it again and it will load fine. However, some commands do not run within the datapack when using Spigot but run fine when not running with Spigot. Example command:
execute as @s[type=trident,nbt={inGround:1b},tag=!UserTPd] at @s as @a[sort=random,limit=1] if score @s PlayerUID = @e[sort=random,type=trident,limit=1] PlayerUID run tag @s add TridentUser
If I take the command apart and just run the first part up it's okay, like so:
execute as @s[type=trident,nbt={inGround:1b},tag=!UserTPd] at @s as @a[sort=random,limit=1] run say test
And running the second part is fine, like so:
execute if score @s PlayerUID = @e[sort=random,type=trident,limit=1] PlayerUID run say test again
But if the command is run as intended, as one long command, it does not run. No error is given.
These issues do not appear in non Spigot versions of server.jar.
Update 1:
Steps to reproduce the issue with the command itself (the command error happens to also occur when run from within the game, so it is not datapack specific) as well as an attached datapack which causes the loading error.
/scoreboard objectives add Test dummy
/scoreboard objectives setdisplay sidebar Test
/summon cow
/scoreboard players set @e[type=cow,sort=nearest,limit=1] Test 5
/scoreboard players set @s Test 5
/execute as @e[type=cow,limit=1] at @s as @a[sort=nearest,limit=1] if score @a[limit=1] Test = @e[sort=nearest,limit=1] Test run say hi
The player should at this point say "hi", but they do not. If you remove
as @e[type=cow,limit=1] at @s
the command will run as expected.
Update 2:
If you also change it so that it is not looking for an entity, but another player, the command will run as expected. It seems to be tied to entities running tests within execute.
