node-minecraft-protocol: Java client throwing DecoderException on client.end
[✅ ] The FAQ doesn’t contain a resolution to my issue
Versions
minecraft-protocol: 1.41.0 server: vanilla node: 18.4.0
Detailed description of a problem
When calling client.end(...) on a connecting 1.19.2 client the connection is lost with the following message: Internal Exception: io.netty.handler.codec.DecoderException: aa: Non [a-z0-9_.-] character in namespace of location: {"text":"no server with subdomain localhost found"}

“no server with subdomain localhost found” is the message I intended to respond to the connecting client.
Current code
const address = await getLocalAddress();
const mcServer = mc.createServer({
'online-mode': false,
host: address,
port: MC_SERVER_PORT,
keepAlive: true,
});
mcServer.on('error', (e) => {
this.logger.error('Error occurred while listening for logins', e);
});
mcServer.on(
'login',
async (client: ServerClient) => {
// lines removed for brevity
client.end("no server with subdomain localhost found");
}
);
mcServer.on('listening', () => {
this.logger.info(
`Listening for login attempts on ${address}:${MC_SERVER_PORT}`,
);
resolve();
});
Expected behavior
String passed into client.end(...) is what appears to the connecting Java client instead of the exception

In my mind this is not something NMP should handle. Docs say otherwise, though. Gonna need an opinion from @rom1504
