Google Ads Api Oauth Catchable Exception

まず、報告された invalid_grant レスポンスを再現ケースとして使用し、vendor/google/auth/src/OAuth2.php と vendor/google/auth/src/Credentials/UserRefreshCredentials.php を通る期限切れ refresh token のパスを追跡します。どの例外が呼び出し元まで到達するのか、またライブラリが信頼できる処理ポイントを提供しているのかを確認します。失敗を区別して予測可能な形で処理でき、その動作についてのテストカバレッジまたはドキュメントがあれば完了です。

        try {
            // Generate a refreshable OAuth2 credential for authentication.
            $oAuth2Credential = (new OAuth2TokenBuilder())
                ->withClientId(env('GOOGLE_ADS_CLIENT_ID'))
                ->withClientSecret(env('GOOGLE_ADS_CLIENT_SECRET'))
                ->withRefreshToken($refreshToken)
                ->build();
        } catch (\Throwable $e) {
            return $this->job->fail();
        }

        try {
            // Construct a Google Ads client configured from a properties file and the
            // OAuth2 credentials above.
            $googleAdsClient = (new GoogleAdsClientBuilder())
                ->withOAuth2Credential($oAuth2Credential)
                ->withDeveloperToken(env('GOOGLE_ADS_DEVELOPER_TOKEN'))
                ->withLoginCustomerId($customerID)
                ->withTransport('rest')
                ->build();
        } catch (\Throwable $e) {
            return $this->job->fail();
        }

So i have the code above which is using the google auth library to create the oauth credential, however some of our clients have expired refresh tokens: This spits out:

Message

Is there a good way to be able to catch that since it's being caught inside the libraries and i'm not seeing a way to properly handle that exception.
