401 (Unauthorized) when subscribing to private-channel (Vue/Laravel) #789

Do you want to request a feature or report a bug? Question/Bug

What is the current behavior? I've set up a Vue3/Laravel app with a live-chat via Pusher which works over non-private channel chat. In the next step I want to use a private channel but something weird happens. The pusher.subscribe function that tries to send a request to /api/pusher/auth doesn't seem to handle the sanctum authorization correctly, resulting in:

POST http://localhost:8000/api/pusher/auth 401 (Unauthorized)

pusher-js.js?v=1974b27b:979 Pusher :  : ["Error: Unable to retrieve auth string from channel-authorization endpoint - received status: 401 from http://localhost:8000/api/pusher/auth. Clients must be authorized to join private or presence channels. See: https://pusher.com/docs/channels/server_api/authorizing-users/"]

This problem is specific to the pusher route, all other api routes work just fine.

Frontend setup

pusher.js:

import Pusher from 'pusher-js'

Pusher.logToConsole = true

const pusher = new Pusher('bf29be46d8eb2ea8ccd4', {
  cluster: 'eu',
  forceTLS: true,
  authEndpoint: 'http://localhost:8000/api/pusher/auth',
  withCredentials: true,
  wsPort: 443,
  wssPort: 443,
  enableStats: false,
  enabledTransports: ['ws', 'wss'],
  auth: {
    headers: {
      'X-Requested-With': 'XMLHttpRequest',
    },
  }
})

export default pusher

axios.js:

import axios from 'axios'

axios.defaults.withCredentials = true

if (import.meta.env.DEV) {
  axios.defaults.baseURL = 'http://localhost:8000'
}

the user is authenticated in a login component:

const signIn = () => {
  axios.get('/sanctum/csrf-cookie').then(() => {
    axios
      .post('/login', form)
      .then(() => {
        store.auth = sessionStorage.auth = 1
        store.signInModal = false
      })
      .catch((er) => {
        state.errors = er.response.data.errors
      })
  })
}

and the app tries to subscribe to pusher in a chat component, only accessible to authenticated users:

const inquireChatSession = () => {
  axios
    .get(`/api/chat/${props.id}`)
    .then((res) => {
      state.chatSessionId = res.data.id
      state.messages = res.data.messages
      state.loadingSession = false

      const channel = pusher.subscribe(`private-chat.${state.chatSessionId}`) // 401 happens here

      channel.bind('App\\Events\\ChatMessageSent', (data) => {
        state.messages.push(data.chatMessage)
      })
    })
    .catch((er) => {
      state.errors = er.response.data.errors
      state.loadingSession = false
    })
}

Backend setup

/routes/api.php:

Route::post('/pusher/auth', function (Request $request) {
    \Log::info('test');

    $user = $request->user();
    if (!$user) {
        abort(403, 'Unauthorized');
    }

    $pusher = new Pusher(
        env('PUSHER_APP_KEY'),
        env('PUSHER_APP_SECRET'),
        env('PUSHER_APP_ID'),
        ['cluster' => env('PUSHER_APP_CLUSTER')]
    );

    $channelName = $request->channel_name;
    $socketId = $request->socket_id;

    $auth = $pusher->socket_auth($channelName, $socketId);

    return response()->json(['auth' => $auth]);
})->middleware('auth:sanctum');

pusher is trying to connect to this route but the authorization fails, resulting in 'test' not being logged and returning aforementioned error back to the client. This seems to be a pusher + sanctum problem because connecting to this diagnostic route works:

Route::post('/pusher/auth', function (Request $request) {
    \Log::info(var_export($request, true));
    \Log::info('Request headers: ', $request->header());
    \Log::info('Request cookies: ', $request->cookies->all());
    \Log::info('Session data: ', $request->session()->all());
    \Log::info('User: ', $request->user());
})

but $request->cookies->all() is empty and $request->user() is null. For some reason no auth cookies are arriving in the pusher route. To check if sanctum works by itself, connecting to the following route, returns the authorized user:

Route::middleware('auth:sanctum')->get('/test-auth', function (Request $request) {
    return $request->user();
});

relevant .env entries:

APP_URL=http://localhost:8000
FRONTEND_URL=http://localhost:3000
SANCTUM_STATEFUL_DOMAINS=localhost:3000
SESSION_DOMAIN=localhost

PUSHER_APP_ID=1728518
PUSHER_APP_KEY=bf29be46d8eb2ea8ccd4
PUSHER_APP_SECRET=...
PUSHER_HOST=
PUSHER_PORT=443
PUSHER_SCHEME=https
PUSHER_APP_CLUSTER=eu

like I said, the entire authentication of the app works fine except the pusher route.

Any idea what the problem is with the pusher route or how I could further debug this? Thank you in advance

What is the expected behavior? Private channel subscription should work.
