NPE when joining servers with a blank mod [urgent?]
xpple opened this issue ยท 13 comments
Whenever one joins a server with a blank (NOTE 1) client-sided Fabric mod, this NPE is thrown
[23:35:27] [main/FATAL] (Minecraft) Error executing task on Client

Along with this error, this warning is also common and is being spammed in the console:
[23:30:26] [main/WARN] (Minecraft) Received passengers for unknown entity
With this warning sometimes also comes an IllegalStateException which says: Invalid entity data item type for field 20 on entity SomeEntity[...]
These errors do not occur once, they are being spammed in the console by an incredible amount.
After six hours of wasted debugging time, I came to the conclusion it must be a Fabric bug.
NOTE 1:
That is, only a main class and a fabric.mod.json, and all the other default files. The Fabric versions are:
dependencies {
minecraft "com.mojang:minecraft:1.16.5"
mappings "net.fabricmc:yarn:1.16.5+build.4:v2"
modImplementation "net.fabricmc:fabric-loader:0.11.1"
modImplementation "net.fabricmc.fabric-api:fabric-api:0.30.3+1.16"
}
minecraft_version=1.16.5
yarn_mappings=1.16.5+build.4
loader_version=0.11.1
fabric_version=0.30.3+1.16
Yes, without your mod. Need to elimate as may varibles as possible to try and figure out whats going on.
Tried it, yes. Even without my mod I'm getting the errors. Seems like Fabric API is the culprit here.
Could very well be, although it happens on almost every server. This is the vanilla log: https://pastebin.com/sUWvpbBd with a whole bunch of errors
