Why is the name "Model" in a controller action not allowed?

Question

I created a new controller action called "AddEmailToCustomerModel"

But I got an exception after trying to call the route:

Exception #0 (Magento\Framework\Exception\RuntimeException): Type Error occurred when creating object: Fekete\Newsletter2Go\Controller\Index\AddEmailToCustomerModel\Interceptor

So I removed the name Model from the action name and its filename, and it works now!

Why does it not work if there is Model in the name?

And are there more reserved words we should know about?

Answer 1

It's working fine with AddEmailToCustomerModel with this action name. This type of error generate when :

1) You inject any class in construct and forgot to remove generated folder. Because, the interceptor file needs to be re-created or refresh.

2) If you forget to inject \Magento\Framework\App\Action\Context $context class in your controller construct and call parent construct.

Hope, it's easy to understand !!
