IronConnector.php Error Argument 1 passed to Illuminate\Queue\Connectors...

When using Iron.io as a queue and run php artisan queue:subscribe we get this error. 8

Problem seems to be in line 208 of

framework / src / Illuminate / Queue / QueueServiceProvider.php

(ie https://github.com/laravel/framework/blob/master/src/Illuminate/Queue/QueueServiceProvider.php#L208 )

Which is:

return new IronConnector($app['request']);

But should be:

return new IronConnector($app['encrypter'], $app['request']);
