[BUG] stream:error code='515' after entering pairing code on phone

[olalonde]

Describe the bug

When entering pairing code on phone, I am getting a 515 code error and the connection closes.

To Reproduce

Baileys 6.4.0. Full reproduction code (just edit BOT_NUMBER):

#!/bin/env node
// Just a single file to help explore/debug the WA protocol and Baileys library
import Baileys, {
  makeWASocket,
  fetchLatestBaileysVersion,
  makeCacheableSignalKeyStore,
  makeInMemoryStore,
  useMultiFileAuthState,
  WAMessageContent,
  WAMessageKey,
  WAVersion,
  AuthenticationState,
  delay,
  isJidBroadcast, // proto,
} from "@whiskeysockets/baileys";
import { mkdir } from "fs/promises";
import path from "path";
import P from "pino";

// enter your phone here
const BOT_NUMBER = "14150001234";
const DATA_PATH = "./data/explore";

export function dbg(val: any) {
  console.dir(val, { depth: null });
}

const logger = P({
  level: "trace",
  transport: {
    target: "pino-pretty",
    options: {
      colorize: true,
    },
  },
});

type Store = ReturnType<typeof makeInMemoryStore>;

interface StartSockConfig {
  store: Store;
  version: WAVersion;
  auth: AuthenticationState;
  saveCreds?: () => Promise<void>;
}

const asyncNoop = async () => {};

// type Sock = ReturnType<typeof makeWASocket>;
async function startSock({
  store,
  version,
  auth,
  saveCreds = asyncNoop,
}: StartSockConfig) {
  const sock = makeWASocket({
    version,
    logger,
    printQRInTerminal: false,
    // using MD api instead
    mobile: false,
    // syncFullHistory: true,
    auth: {
      ...auth,
      /** caching makes the store faster to send/recv messages */
      keys: makeCacheableSignalKeyStore(auth.keys, logger),
    },
    // msgRetryCounterCache,
    generateHighQualityLinkPreview: true,
    shouldIgnoreJid: (jid) => isJidBroadcast(jid),
  });

  // store?.bind(sock.ev);

  // Pairing code for Web clients
  if (!sock.authState.creds.registered) {
    console.log(
      "Waiting 5s for socket to be ready, otherwise we get 428 Precondition Required error and the socket disconnects..."
    );
    await delay(5000);
    const phoneNumber = BOT_NUMBER;
    console.log({ phoneNumber });
    console.log("Requesting pairing code...");
    const code = await sock.requestPairingCode(phoneNumber);
    console.log(`Pairing code: ${code}`);
  }

  // the process function lets you process all events that just occurred
  // efficiently in a batch
  sock.ev.process(async (event) => {
    dbg({ event });
    // credentials updated -- save them
    if (event["creds.update"]) {
      await saveCreds();
    }
  });
}

export async function createBot() {
  // fetch latest version of WA Web
  const { version, isLatest } = await fetchLatestBaileysVersion();
  console.log(`using WA v${version.join(".")}, isLatest: ${isLatest}`);

  // the store maintains the data of the WA connection in memory
  // can be written out to a file & read from it
  const store = makeInMemoryStore({ logger });
  const storePath = path.join(DATA_PATH, "store", "store_multi.json");
  // creates path if it doesn't exist
  await mkdir(path.dirname(storePath), { recursive: true });
  store.readFromFile(storePath);
  // save every 10s
  setInterval(() => {
    store.writeToFile(storePath);
  }, 10_000);

  // Load auth state if previously saved
  const { state: auth, saveCreds } = await useMultiFileAuthState(
    path.join(DATA_PATH, "auth")
  );
  // console.log("Loaded auth:");
  // dbg({ auth });

  // start a connection

  return await startSock({ store, version, auth, saveCreds });
}

await createBot();

Expected behavior

There should be no error.

Environment (please complete the following information):

• Is this on a server? On my macbook air.
• What do your connectOptions look like? See reproduction code.
• Do you have multiple clients on the same IP? Just my WhatsApp for Mac but connected to a different number.
• Are you using a proxy? No.

Additional context

See reproduction code.

retry with

// Pairing code for Web clients
  if (!sock.authState.creds.registered) {
    const phoneNumber = BOT_NUMBER;
    console.log({ phoneNumber });

    await sock.waitForConnectionUpdate((update) => !!update.qr) 

    console.log("Requesting pairing code...");
    const code = await sock.requestPairingCode(phoneNumber);
    console.log(`Pairing code: ${code}`);
  }

Thanks. That seemed to work.

Oops, never mind. I just deleted my auth state, "logged out" the device form my phone and tried again. Same error as before.

edit: It does avoid the 5s delay hack I had before though, but doesn't solve the issue.

it is possible that you share the error that you are presenting

You need to implement reconnect logic because when the connection is successful to log in the first time, you need to restart the connection https://github.com/WhiskeySockets/Baileys/blob/555cc9b3145ea2a94aeb34eec30eb966154b16f8/Example/example.ts#L149-L162

Ok thanks, that works.
