Unexpected exception when instantiating class - error in Symfony 5.4 and PHP 8.1

[JakubSzubart]

Hey

Today out of nowhere i got error Unexpected exception when instantiating class. when i tried to create client class for my akeneo integrator app.

• PHP: 8.1
• Symfony: 5.4

$clientBuilder = new AkeneoPimClientBuilder($params->get('pim_url'));
$this->client = $clientBuilder->buildAuthenticatedByPassword(
    $params->get('pim_api_client_id'),
    $params->get('pim_api_client_secret'),
    $params->get('pim_api_user'),
    $params->get('pim_api_password')
);

Additional informations: The error appeared after i installed the Symfony bundle https://symfony.com/bundles/SensioFrameworkExtraBundle/current/index.html#installation.

I tried to remove vendors and composer.lock file and reinstall packages. Still error is visible.

Can somebody help me?

I solved the problem, i missed in my composer.json file one of required packages:

• http-interop/http-factory-guzzle

SensioFrameworkExtraBundle was not a problem. Some code was not merge correctly with my coworkers, and the library disappeared.

My advice: always double check requirements of the library 👍
