We’re using Google APIs Client Library for PHP (https://github.com/googleapis/google-api-php-client) using authentication with Service Accounts.
The code is
putenv('GOOGLE_APPLICATION_CREDENTIALS=' . $google_api_key_file_path);
$client = new Google_Client();
$client->setApplicationName('Google Translate API');
$client->useApplicationDefaultCredentials();
$client->addScope(Google_Service_Translate::CLOUD_TRANSLATION);
$service = new Google_Service_Translate($client);
$projects = $service->projects;
$postbody = new Google_Service_Translate_TranslateTextRequest();
$postbody->setContents($contents);
$postbody->setSourceLanguageCode($source_lang);
$postbody->setTargetLanguageCode($target_lang);
$result = $projects->translateText('projects/myproject', $postbody)->translations;
The code worked fine until about a month ago, but now returns this error:
{ "error": { "code": 403, "message": "Request had insufficient authentication scopes.", "errors": [ { "message": "Insufficient Permission", "domain": "global", "reason": "insufficientPermissions" } ], "status": "PERMISSION_DENIED", "details": [ { "@type": "type.googleapis.com/google.rpc.ErrorInfo", "reason": "ACCESS_TOKEN_SCOPE_INSUFFICIENT", "domain": "googleapis.com", "metadata": { "service": "translate.googleapis.com", "method": "google.cloud.translation.v3.TranslationService.TranslateText" } } ] } }
Nothing has changed at the code level or at the account settings level on Google.
The API are enabled and the same Service Account works fine with other APIs.
We tried disabling and re-enabling the API again.
