The error
"Reason for failure: Invalid arguments or no arguments provided"
will happen if the console route has not been registered.
Is that your full module.config.php? I assume you just excluded the return statement for the array from the code snippet and it really is there in the module.config.php in your application?
Also is this in a separate module? Have you definitely included the module in config/application.config.php
as everything seems ok with the code
