Laravel Passport: Ignore login errors

At work we built a web application consisting of one backend that provides an API for user management and login via OAuth2, and a couple of frontend applications that all rely on that API. ​

For OAuth2, we used the Laravel 5.6 Passport library that brings all the OAuth2 server stuff we needed. ​

One issue we had were exceptions that occured in the API and were logged in our own Sentry instance: One entry for every user that mis-typed his password: ​

League\OAuth2\Server\Exception\OAuthServerException ​

The user credentials were incorrect. ​

​

To solve this issue, we added the following code to our API application's exception handler: ​

    /**
     * Determine if the exception is in the "do not report" list.
     *
     * @param Exception $e Exception to check
     *
     * @return bool
     */
    protected function shouldntReport(Exception $e)
    {
        if ($e instanceof \League\OAuth2\Server\Exception\OAuthServerException) {
            //6: The user credentials were incorrect
            return $e->getCode() == 6;
        }
 
        return parent::shouldntReport($e);
    }
