Laravel 5 - Interface is not instantiable

This error message in Laravel 5 typically means that you are trying to instantiate an interface, but interfaces cannot be instantiated because they are only a contract for the methods that a class should implement. You should instead create a class that implements the interface and then instantiate an object of that class.

It's also possible that the class that you are trying to instantiate has not been properly bound to an implementation in the service container. In this case, you should ensure that you have properly bound the interface to an implementation using Laravel's service container.

If you are unsure about how to resolve this issue, you should provide more information about the specific code that is causing the error and the environment in which you are running the code.
