OAuth 2.0 - Integration Setup error

Hi Team, I am trying to integrate my application with Creatio OAuth 2.0 using( Grant type - authorization code). 

I created a URL with right client_id and redirect_uri 

https://xxxx-demo.creatio.com/0/connect/authorize?client_id=xxxxxx&redirect_uri=https://my_redirect_uri&response_type=code&scope=Test&state=1a4741d705c02f0c8f6e00d68e38ec7f

When I click the above link, it takes uses to username/password page, then to consent page. Once the user accepts the consent page info, it gives the below error, "Integration setup error"(See screenshot).

One thing that's not clear is scope. I have currently set it to the "Name"(Test) field that we specify in the Settings->OAuth 2.0 Integrated Application. I even tried using various other scopes as "offline_access" based on the below doc(https://academy.creatio.com/docs/8.x/dev/development-on-creatio-platfor…) , but it doesn't make any difference.
