Error with Pusher while publishing content in Laravel 9 PHP 8.1

Question

I'm currently updating a Qr online platform using Pusher in Laravel 9.52 and PHP 8.1.10.

I have an issue with the confirmation of my Qr code when they're scanned here's the laravel.log line

"exception":"[object] (Pusher\\ApiErrorException(code: 0): cURL error 6: Could not resolve host: api-.pusher.com ... at /public/vendor/pusher/pusher-php-server/src/Pusher.php:782

Here's the lines in Pusher.php

public function trigger($channels, string $event, $data, array $params = [], bool $already_encoded = false): object
{
    $post_value = $this->make_trigger_body($channels, $event, $data, $params, $already_encoded);
    $this->log('trigger POST: {post_value}', compact('post_value'));
    return $this->process_trigger_result($this->post('/events', $post_value)); (the exception is pointing here)
}

We're using "pusher/pusher-php-server": "7.2.0" we didn't have this error in Laravel 8.83 (previous version that was using pusher-php-server : 4)

Do you know if there are any incompatibilities in Laravel 9 with Pusher? Do you have any leads for an answer?

Thanks a lot in advence.
