Latest build makes impossible to join some of my network spigot servers 1.19 seems fine tho

all I can see is that sometning apparently sent bad json in a packet, you can run the server with -Dwaterfall.packet-decode-logging=true to maybe get more info, but, not much for me to go off here, general reproduce without plugins, etc

it is most likely caused by one off our plugins i will stay on 1.19 for the moment i'll run the command you provided tomorrow

thanks

Hi, we're facing the same issue. Seems like it's triggered when sending empty/blank messages from a server:

io.netty.handler.codec.DecoderException: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Not a JSON Object: [" "]

We have the same issue when players try to join our servers with 1.20.3. https://paste.gg/p/anonymous/8f54662e04084e1cbf7a83725d3e3a0e
