cakephp: UrlHelper can't match with any defined routes if missing _method option

This is a (multiple allowed):

• bug

• enhancement

• feature-discussion (RFC)

• CakePHP Version: 3.5.6

• Platform and Target: PHP built-in webserver

What you did

In routes.php I declared a route like this:

$routes->connect('/login', ['controller' => 'Users', 'action' => 'login'], ['_name' => 'login'])->setMethods(['GET', 'POST']);

In the template file, I uses UrlHelper like this:

$this->Url->build(['_name' => 'login'])

What happened

I get Cake\Routing\Exception\MissingRouteException and an error Warning (2): strtoupper() expects parameter 1 to be string, array given [CORE/src/Routing/Route/Route.php, line 744]

What you expected to happen

It should match with the route that I have declared in routes.php and return /login string. The error will gone if I’m also add _method option like this:

$this->Url->build(['_name' => 'login', '_method' => 'GET'])

I think it should not matter what http method will be used the url to be generated is /login
