SLS-02 test case fails with Message: Fatal Error: no implicit conversion of nil into String

[sourabhjain12]

I am running smart tests in the command line with sequences SMARTDiscoverySequence, ManualRegistrationSequence, and StandaloneLaunchSequence.

I am getting the following result for StandaloneLaunchSequence Sequence:
✓ pass - SLS-01 OAuth 2.0 authorize endpoint secured by transport layer security
X fail - SLS-02 OAuth server redirects client browser to app redirect URI Message: Fatal Error: no implicit conversion of nil into String
skip - SLS-03 Inferno client app receives code parameter and correct state parameter from OAuth server at redirect URI
Message: Redirect to OAuth server failed
✓ pass - SLS-04 OAuth token exchange endpoint secured by transport layer security
skip - SLS-05 OAuth token exchange fails when supplied invalid code Message: Redirect to OAuth server failed
skip - SLS-06 OAuth token exchange fails when supplied invalid client ID Message: Redirect to OAuth server failed
skip - SLS-07 OAuth token exchange request succeeds when supplied correct information Message: Redirect to OAuth server failed
skip - SLS-08 Token exchange response body contains required information encoded in JSON Message: Redirect to OAuth server failed
skip - SLS-09 Response includes correct HTTP Cache-Control and Pragma headers Message: Redirect to OAuth server failed

Please notice the failing test case SLS-02. I am sure I have provided all the correct details as the tests work in the normal web application (http://localhost:4567)

Here is my script.json
