Console Error
Bug Description
When a 1.20.2 client joins a 1.16.5 server, the error message ERROR IN Protocol1_17To1_16_4 IN REMAP OF ENTITY_METADATA is spammed in the logs and sometimes the player's connection times out while joining.
Steps to Reproduce
- Host a 1.16.5 fabric server with viafabric
- Connect to the server with a 1.20.2 client
- Observe the error in the server log
Expected Behavior
This error should not occur while the player is joining.
Additional Server Info
Checklist
- I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
- I have included a ViaVersion dump.
- If applicable, I have included a paste (not a screenshot) of the error.
- I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.
This is likely caused by a bad third-party mod, Please perform a binary search to see what causes viafabric to complain about bad entity metadata packets being sent to server.
I still experience this issue after removing all mods except for viafabric and fabric api.
I have also updated the initial message to include the full log, without only these two mods installed.
Can you test this on a clean world that has no data on it? if it still happens from there, you might have to update viafabric + viaversion jars to latest CI builds.
Then something bad has been stored in the world save. (possibly corrupt data or bad NBT items/blocks/etc is hidden somewhere)
