[1.16.1] Mod won't work in server environment

Hi y'all,

I'm reaching out because I'm truly at a loss on why this isn't working. I just built my mod on 1.16.1 for the first time to test with my friend, but neither of us can connect, getting booted on join. I have narrowed it down to being an issue with my mod, as we can join a Forge server with no mods on it. The connection in-game shows:

Internal Exception: io.netty.handler.codec.DecoderException: io.netty.handler.codec.EncoderException: java.io.UTFDataFormatException: malformed input around byte 83

 

However I cannot find this in either server or client log at all. Any advice on this issue?

Start the Forge server with -Dforge.logging.mojang.level=DEBUG. Then the exception should be logged to debug.log.

I confirmed that this log provides the same info when it matters, upon player join. Nothing additional could be learned from adding this. The paste is too large to post.

I derped, you receive this error message on the client, right? Then the VM argument needs to be on the client of course. Sorry.

Thank you! Thank you very much. I appreciate your advice and using it I can now diagnose myself using the stack trace. Thank you again. :)
