If you join a server which downloads a resource pack twice in quick succession, this error is given:
Error sending packet serverbound/minecraft:resource_pack
io.netty.handler.codec.EncoderException: Sending unknown packet 'serverbound/minecraft:resource_pack'
Reproduce:
- Set up a Minecraft server
- Point the resource-pack line in server.properties to a resource pack
- Start the server
- Join the server, cancel the connection shortly after (making sure the resource pack starts downloading), and then rejoin
It may take a few tries, but eventually you will get a "Failed to connect to the server" screen, showing the error.
After quickly looking at the recording I attached, it appears to error when timing the rejoin where the second resource pack starts downloading right as the first one finishes downloading. This could be wrong though.
