Access token is required even if `handler` configuration parameter is set

We recently changed our Rollbar configuration so that it uses fluentd td-agent for logging errors. So we added :

handler: fluent
fluent_tag: identifier_for_component_logging_to_rollbar

to the configuration file and of course removed the access_token variable as it is no longer needed since this is now added to the configuration file of the td-agent daemon. However running composer install fails with:

Adding a false access token resolves this issue, and of course Rollbar works as expected.

Wouldn't it make more sense to check if fluent handler is used and if so, to not call the

private function setAccessToken($config)
    {
        if (isset($_ENV['ROLLBAR_ACCESS_TOKEN']) && !isset($config['access_token'])) {
            $config['access_token'] = $_ENV['ROLLBAR_ACCESS_TOKEN'];
        }
        $this->utilities->validateString($config['access_token'], "config['access_token']", 32, false);
        $this->accessToken = $config['access_token'];
    }

method which in turn calls the validateString method that generates this error ?
