No callbacks on private channel. pusher:subscription_error

[brada1703]

Hey everyone,

I had Pusher working fine before updating a few packages. Now I am getting the following error:

"Error: JSON returned from channel-authorization endpoint was invalid, yet status code was 200. Data was:...

And

Pusher : : ["No callbacks on private.... for pusher:subscription_error"]

Within the Debug Console, I can see that the channel is disconnecting.

I am using:

• PHP 8.1
• Laravel 9.24.0
• Pusher / Pusher-php-server 7.0.2

My code:

import Echo from 'laravel-echo';

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    cluster: process.env.MIX_PUSHER_APP_CLUSTER,
    forceTLS: true
});

Is my error here simply due to using PHP8.1? Is it still not supported? If no, does anyone have a work around or do I have to downgrade my app?

Hi @brada1703. I believe you raised a support ticket regarding this, but we haven't had a response from you. Are you able to respond there? It would be useful to review the full error message (including the data that was included in the error message).

hey @brada1703 . i hope you are doing well. can you please check on this ... https://github.com/pusher/pusher-http-php/issues/348#issuecomment-1267373926

also maybe ... you did not state authEndpoint: '/broadcasting/auth' param in Echo configuration.

This was dealt with separately with the Pusher support team.

This was a CORS issue where config/cors.php did not correctly specify the auth endpoint.
