Laravel dependency injection "not instantiable" - php

Question

I have spent a day trying debugging and trying to understand what is going wrong but...
So here is my code:
<?php
namespace RememberCalories\Rest;
interface MyJsonResponseInterface
{
public function getResponse();
}
And here is the class which I want to inject:
<?php
namespace RememberCalories\Rest;
class MyJsonResponse implements MyJsonResponseInterface
{
protected $success;
protected $responseCode;
protected $responseMsg;
protected $data;
public function __construct($data, $responseCode=0, $responseMsg='')
{
$this->data = $data;
$this->responseCode = $responseCode;
$this->responseMsg = $responseMsg;
if ( $this->responseCode === 0 ) {
$this->success = true;
}
}
...
Binding:
\App::bind('MyJsonResponseInterface', function($app, $parameters) {
$obj = new \RememberCalories\Rest\MyJsonResponse(null);
// var_dump($obj);
// die();
return $obj;
});
And at last the controller:
<?php
use \RememberCalories\MainMenu\MainMenu;
use \RememberCalories\Repository\TargetEloquentRepository as TargetRepository;
use \RememberCalories\Rest\MyJsonResponseInterface;
//use \RememberCalories\Rest\MyJsonResponse;
class BaseController extends Controller
{
protected $viewVars;
protected $mainMenu;
//Dependency injection classes
protected $target;
protected $myJsonResponse;
public function __construct(TargetRepository $target, MyJsonResponseInterface $myJsonResponse )
{
$this->beforeFilter('accessFilter');
$this->target = $target;
//$this->myJsonResponse = $myJsonResponse;
$this->mainMenu = (new MainMenu())->build();
$this->prepareViewVariables();
}
So the problem is with the second parameter of BaseController: MyJsonResponseInterface. The first is injected without problems but this one I get an error:
Illuminate \ Container \ BindingResolutionException
Target [RememberCalories\Rest\MyJsonResponseInterface] is not
instantiable.
It seems that the Closure in \App::bind('MyJsonResponseInterface' ...) is not called.
I have moved it to service provider with the same result.
But at the same if to call manually \App::make('MyJsonResponseInterface') everything is created ideally.
Please advise what way to investigate.

You need to App::bind the full namespace - so in your example, App::bind('RememberCalories\Rest\MyJsonResponseInterface').
