Prompt adaptive script function not properly working with remove_on_consume_from_api="true" config

[dewniMW]

Configure an adaptive script with the prompt function and try the authentication flow.

var onLoginRequest = function(context) {
   executeStep(1, {
       onSuccess: function (context) {
           var username = context.steps[1].subject.username;
           prompt("genericForm", {"username":username, "inputs":[{"id":"fname","label":"First Name"},{"id":"lname","label":"Last Name"}]}, {
             onSuccess : function(context) {
                var fname = context.request.params.fname[0];
                var lname = context.request.params.lname[0];
                Log.info(fname);
                Log.info(lname);
             }
           });
       }
   });
}

The prompt function will work as shown below.

Now add the following config (https://is.docs.wso2.com/en/latest/apis/use-the-authentication-rest-apis/) in the deployment.toml and retry the authentication flow after a server restart.

[authentication.endpoint.redirect_params]
filter_policy = "exclude"
remove_on_consume_from_api = "true"
parameters = ["ske"]

The input fields are missing in the UI as shown below.

If we remove remove_on_consume_from_api = "true" from the config and try the flow, then it works correctly. As per the analysis https://github.com/wso2/identity-apps/blob/master/identity-apps-core/apps/authentication-portal/src/main/webapp/dynamic_prompt.jsp#L55 becomes null when remove_on_consume_from_api = "true"
