Issue with namespace. Using method from wrong object

Question

I'm having an issue with my code below. The error I get is:

Catchable fatal error: Argument 1 passed to Closure::QuizApp\Routes{closure}() must be an instance of QuizApp\Routes\ServerRequestInterface, instance of Slim\Http\Request given in /var/www/QuizApp/Routes/AuthRoutes.php on line 8

Is this because I'm declaring a namespace at the top? I can solve it by using an alias, but I'm curious as to why it's happening in the first place.

<?php

namespace QuizApp\Routes;

use \Psr\Http\Message\ServiceRequestInterface;
use \Psr\Http\Message\ResponseInterface;

$app->get('/login', function(ServerRequestInterface $req, ResponseInterface $resp) use ($config) {

    $callback = $config['site']['domain'] . $this->router->pathFor('fb_callback');
    return $this->FBAuthServices->redirect_to_auth_page($config['facebook']['permission'],
                                                        $callback);

});

Edit After looking at my own code, I realize I don't even need the namespace. The class that was in this file, has now been moved out. Would still love an answer though, I'm curious.

Compare these

must be an instance of QuizApp\Routes\ServerRequestInterface

use \Psr\Http\Message\ServiceRequestInterface;

It's a typo, it should be named ServerRequestInterface in the use.

My word. I feel like a right prat now. Thank you Sven. When I used the alias I copied it from the other file I had open, then :u to undo, hence why it worked, then failed when I removed. ha ha. /facepalm
