Error when connecting to server

let opts = {
    // For production launchers, I recommend not passing 
    // the getAuth function through the authorization field and instead
    // handling authentication outside before you initialize
    // MCLC so you can handle auth based errors and validation!

Minecraft is starting, and closing after it
