I have also validated the the Jwt Exchange via Postman and I am able to get a jwt token using the auth code I receive from login.
I have no details of the error other than 'No Configuration Available', what are possible next step to assist me in troubleshooting the issue if I already have an Authenication setup?
It looks like that Messenger cannot retrieve the configuration.
This could be a network issue or a setting issue.
Check in the network tab that Http calls to Genesys domain are not blocked.
Check your configuration on GC side.
It might be that your deployment is not linked to your configuration. Hence the error.
If the link is ok, then check that the right deploymentId is specified in Messenger.
From the deploymentId, Messenger will fetch the configuration linked to it.
