[hammadev]

The error i got on pusher debug console

here's my code

async function iniPusher() {
    const pusher = Pusher.getInstance();

    await pusher.init({
      apiKey: '',
      cluster: 'ap2',
      authEndpoint: `https://domain.com/api/v1/pusher/user-auth/${auth.user.id}`,
    });

    await pusher.connect();
    await pusher.subscribe({
      channelName: 'private-chat.' + auth.user.id,
      onEvent: event => {
        console.log(`Event received: ${event}`);
        const formattedData = formatEventData(event);
        setMessages(previousMessages =>
          GiftedChat.append(previousMessages, formattedData),
        );
      },
      onConnectionStateChange(currentState) {
        console.log(`Connection: ${currentState}`);
      },
      onError(message, code, e) {
        console.log(`onError: ${message} code: ${code} exception: ${e}`);
      },
      onSubscriptionSucceeded(channelName, data) {
        console.log(`onSubscriptionSucceeded: ${channelName} data: ${data}`);
      },
      onSubscriptionError(channelName, message, e) {
        console.log(
          `onSubscriptionError: ${message} channelName: ${channelName} Exception: ${e}`,
        );
      },
      onAuthorizer(channelName, socketId) {
        console.log(
          `calling onAuthorizer. channelName=${channelName}, socketId=${socketId},`,
        );

    });
  }

response I got from server

{
    "auth": "d980932ee394770d0950:50b4795375582e8dceb2a6597b8eab6f2f72c23e25b1ee9aa5fc9de9f2160e3f",

Do you receive this every time you attempt to subscribe? This is the result of an incorrect token specified either in the client or server - https://docs.bird.com/pusher/channels/channels/troubleshooting/why-am-i-receiving-the-invalid-signature-expected-hmac-sha256-error

yes, I receive this error every time, but the server correctly generates an auth token and on the client side, I haven't identified any errors.

It might generate a token, but the token appears to be using incorrect values. You should ensure the key provided to the client is correct, along with the app id, key and secret provided to the generating server is valid.

Yes, I checked all values are the same and valid, even though it works fine in public channels.

Could you get in touch with us at [email protected]? This was you can share more of your code and the keys being used so I can look to replicate
