#Exception handling

Every request made with the client can throw an HTTP exception.

#HTTP exception

The parent of these HTTP exceptions is Akeneo\Pim\Exception\HttpException. You can get the request and the response that are responsible for this exception. Also, the HTTP response code and response message are available.

try {
        $client->getProductUuidApi()->get('1cf1d135-26fe-4ac2-9cf5-cdb69ada0547');
    } catch (HttpException $e) {
        // do your stuff with the exception
        $requestBody = $e->getRequest()->getBody();
        $responseBody = $e->getResponse()->getBody();
        $httpCode = $e->getCode(); 
        $errorMessage = $e->getMessage(); 
    }
    

Two types of exception inherit from this exception: server exception and client exception.

#Server exception (5XX)

A server exception thrown by the client means that the server failed to fulfill an apparently valid request. It's an HTTP code from the 5xx family.

#Not found exception (404)

    } catch (UnprocessableEntityHttpException $e) {
        // do your stuff with the exception

        $httpCode = $e->getCode(); 
        $errorMessage = $e->getMessage(); 
        $errors = $e->getResponseErrors();
        foreach ($e->getResponseErrors() as $error) {
            // do your stuff with the error
            echo $error['property'];
