I did what the documentation said, but I ran into this problem

[ghost]

TypeError
Argument 1 passed to filsh\yii2\oauth2server\Server::handleAuthorizeRequest() must be an instance of OAuth2\RequestInterface or null, boolean given, called in E:\www\wwwroot\passport2.sh-helpdesk.com\frontend\controllers\SiteController.php on line 71

Can you show how your code looks like?
I have not been dealing with this library for quiet some time, so I need a bit of details to be able to help.
Am Planning to replace this library with one implementing phplague/oauth2 but time to put things together is a challenge for now.

Till then, I would be happy to get information so that I can help you get past that!
