JSON key is missing the type field

Question

I try to connect to my Google Calendar using the Google API for PHP, version 2.2.0. Until now I do not succeed in connecting to my calendar and that is very frustrating.

At this moment I receive the following fatal error:

Fatal error: Uncaught InvalidArgumentException: json key is missing the type field in /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/vendor/google/auth/src/CredentialsLoader.php:123 Stack trace: #0 /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/vendor/google/auth/src/ApplicationDefaultCredentials.php(154): Google\Auth\CredentialsLoader::makeCredentials('https://www.goo...', Array) #1 /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/src/Google/Client.php(1078): Google\Auth\ApplicationDefaultCredentials::getCredentials('https://www.goo...') #2 /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/src/Google/Client.php(365): Google_Client->createApplicationDefaultCredentials() #3 /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/src/Google/Client.php(786): Google_Client->authorize() #4 /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/src/Google/Service/Resource.php(232): Google_C in /home/servi471/public_html/wp-content/plugins/google-api-php-client-2.2.0/vendor/google/auth/src/CredentialsLoader.php on line 123

I use this code:

require_once WP_PLUGIN_DIR . '/google-api-php-client-2.2.0/vendor/autoload.php';
require_once WP_PLUGIN_DIR . '/google-api-php-client-2.2.0/src/Google/Client.php';
require_once WP_PLUGIN_DIR . "/google-api-php-client-2.2.0/vendor/google/apiclient-services/src/Google/Service/Calendar/Resource/CalendarList.php";
require_once WP_PLUGIN_DIR . "/google-api-php-client-2.2.0/vendor/google/apiclient-services/src/Google/Service/Oauth2.php";


putenv('GOOGLE_APPLICATION_CREDENTIALS=' . dirname(__FILE__) . '/oauth-credentials.json');

$client = new Google_Client();
$redirect_uri = 'https://myredirect-uri';
$client->setRedirectUri($redirect_uri);

$client->setRedirectUri($redirect_uri);
$client->setClientId('myclient-di.apps.googleusercontent.com');
$client->setClientSecret('myclient-secret');
$client->setAccessType("offline");        // offline access
$client->setIncludeGrantedScopes(true);   // incremental auth
$client->addScope(Google_Service_Calendar::CALENDAR);

$user_to_impersonate = 'owner-of-agenda@gmail.com';
$client->setSubject($user_to_impersonate);
$client->setAuthConfig(GOOGLE_APPLICATION_CREDENTIALS);

$client->useApplicationDefaultCredentials();

if (file_exists(CREDENTIALS_PATH)) {
    $token = file_get_contents(CREDENTIALS_PATH);
    echo "<h4>_Token</h4>";
    var_dump($token);
    $client->setAccessToken($token);
}
echo "<br><br>CLIENT";

$service = new Google_Service_Calendar($client);

$calendarList = $service->calendarList->listCalendarList();
var_dump($calendarList);

echo "<h4>End of example</h4>";

I see that an token is generated.

Could someone please assist me in making this connection?

I solved it, The JSON-key-file did not contain the type field. But I removed some statements and went back to the minimum of data. Added also the statement:

$client->setApprovalPrompt('force');
