Swagger Oauth2 Invalid Request

I’m using OpenEmr Express from AWS, and I registered a client however I can’t authorize with built-in swagger:

After this step it takes me to a login page. When I enter the username and password (admin, instance id). It gives me an “invalid request” response:
Capture

I am not sure if I’m entering the correct username and password but that’s the only username and password I have. Do I need to somehow attach a user to this app?

Hi @Ahmet,

Did you enable the App, This can be verified by going to Globals>System>API clients and check after you created the app did you enable it .
