Laravel magazines in Heroku do not appear

Question

I applied the Laravel app to heroku following the official guide. He says change APP_LOG=errorlogwhat I did.

I also tried two different versions of this, the commented line is a variation.

$this->app->configureMonologUsing(function($monolog){ // $monolog->pushHandler(new \Monolog\Handler\SyslogHandler('papertrail')); $monolog->pushHandler(new \Monolog\Handler\StreamHandler('php://stderr', \Monolog\Logger::WARNING)); });

If I use Log :: error ("something"), I cannot see anything. I look at both papertrail and the CLI commandheroku logs --tail --app {appname}
