get_in fails when a key in the path has a value other than array

[davidPaymefy]

I believe get_in is all about safe navigation and this case should return the default value instead of failing with a TypeError.

$user = [
            'username' => 'Peter',
            'profile'  => null,
        ];

$this->assertSame('fakepass', get_in(['profile', 'password'], $user, 'fakepass'));

PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in
