NotFoundHttpException in Handler.php line 103

This happens when I add a basic route (foo). The rest of the routes work as expected. This generates a NotFoundHttpException and a ModelNotFoundException.

app/Http/routes.php:

Route::auth();

Route::get('/home', 'HomeController@index');

Route::get('/index','WosController@index');
Route::get('/create','WosController@create');
Route::get('/{workorder}','WosController@show');
Route::post('/create','WosController@store');

Route::get('/', function () {
    return view('welcome');
});

Route::get('/foo', function () {
    return view('foo');
});

app/resources/views/foo.blade.php:

<p>foo</p>
