**What does this error mean?**

You can read the context log of this issue at https://github.com/switchupcb/disgo/issues/81.

Here is the code involved.

```json
{"level":"info","time":"2025-02-25T11:15:50.047882793Z","session":"19a66158dd23faa53df0a0cce17ea441","client":"948649712649662524","message":"received signal: <-s.Context.Done with state \"connected\""}
```

This log is output at https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_manager.go#L114

```json
{"level":"info","time":"2025-02-25T11:15:50.064255893Z","session":"19a66158dd23faa53df0a0cce17ea441","client":"948649712649662524","error":"listen: failed to get reader: failed to read frame header: EOF","message":"<-s.Context.Done manager wait error result"}
```

This log is output at [`unimplemented in public`](https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_manager.go#L120) which contains `LogSession(Logger.Info(), s.ID).Str(LogCtxClient, bot.ApplicationID).Err(err).Msgf("<-s.Context.Done manager wait error result")`
- from `return err` at https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_listener.go#L40
- from `socket.Read` at https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_listener.go#L19

Start with wrapper/session_routine_listener.go at lines 19 and 40, then inspect wrapper/session_routine_manager.go at lines 114 and 120. Use the linked context log to trace the EOF after Context.Done and determine whether it represents an expected disconnect or an unhandled error. Done means the cause and intended handling are documented or agreed on before implementation.
