GET of Group Settings doesn´t work: response is XML instead of JSON

[Conjacq]

The GET request of the Group Setting API returns XML, but the google-api-php-client-services expects JSON. It returns an empty Google\Service\Groupssettings class.

Environment details

• PHP version: 8.3.6

Composer packages:

• google/apiclient v2.18.3
• google/apiclient-services v0.397.0

Steps to reproduce

1. Use the GET function of \Google\Service\Groupssettings
2. The result will be an empty \Google\Service\Groupssettings class

Workaround

The PATCH request will return a JSON response and that works without a problem. It is possible to alter 1 deprecated setting via the PATCH request and all the current settings will be returned.

JSON decode in the REST class

The REST class is decoding the response and expects JSON:

    /**
     * Decode an HTTP Response.
     * @static
     *
     * @template T
     * @param RequestInterface $response The http response to be decoded.
     * @param ResponseInterface $response
     * @param class-string<T>|false|null $expectedClass
     * @return mixed|T|null
     * @throws \Google\Service\Exception
     */
    public static function decodeHttpResponse(
        ResponseInterface $response,
        ?RequestInterface $request = null,
        $expectedClass = null
    ) {
        $code = $response->getStatusCode();

        // retry strategy
        if (intVal($code) >= 400) {
            // if we errored out, it should be safe to grab the response body
            $body = (string)$response->getBody();

            // Check if we received errors, and add those to the Exception for convenience
            throw new GoogleServiceException($body, $code, null, self::getResponseErrors($body));
        }

        // Ensure we only pull the entire body into memory if the request is not
        // of media type
        $body = self::decodeBody($response, $request);

        if ($expectedClass = self::determineExpectedClass($expectedClass, $request)) {
            $json = json_decode($body, true);

            return new $expectedClass($json);
        }

        return $response;
    }
