[1.18.2] Network error on login

[Skyriis]

Hey Guys,
it looks like i broke something in my mod but i got no idea what.
This happends if i try to join the `runServer` Server with my `runClient` Client

Full Error (Client Side): https://mclo.gs/AjEXFD1

Any ideas what could cause that?

The error says there is something wrong with your codec.

Usually, it's a mismatch between the encode/decode methods, such as forgetting to read/write a field in one of them. Or doing the fields in a different order.

 

For you it is trying to decode a string which is sent over the network in UTF format. But it is not valid UTF in that part of the buffer when it comes to reading it.

So it's probably not your expected string.

 

You can either add a breakpoint at the UTFDataFormatException constructor to see what the problem is,

or enable debug logging for Mojang's network code so you can see the full stacktrace:

you would need to add the property to your run configurations in the build.gradle or your IDE's run configurations.
