[keycloak-user] registration new flow

Hi all, I am using Keycloak 3.2.1 and trying to add a new flow step to the new user registration flow so that I can add a script execution step as illustrated in the attached image. However, with this configuration I am getting a nullpointer exception when I click on the "Register" link and get a 500 error instead of the registration page. Does anyone have any ideas what I might be doing wrong or if there is a different way to accomplish what I am trying to do? The stack trace from the log is below: Thanks Stephen 22:42:11,855 WARN [org.keycloak.services] (default task-1) KC-SERVICES0013: Failed authentication: java.lang.NullPointerException at org.keycloak.authentication.FormAuthenticationFlow.renderForm(FormAuthenticationFlow.java:281) at org.keycloak.authentication.FormAuthenticationFlow.processFlow(FormAuthenticationFlow.java:263) at org.keycloak.authentication.DefaultAuthenticationFlow.processFlow(DefaultAuthenticationFlow.java:127) at org.keycloak.authentication.AuthenticationProcessor.authenticateOnly(AuthenticationProcessor.java:843) at org.keycloak.authentication.AuthenticationProcessor.authenticate(AuthenticationProcessor.java:714) at org.keycloak.services.resources.LoginActionsService.processFlow(LoginActionsService.java:279) at org.keycloak.services.resources.LoginActionsService.processRegistration(LoginActionsService.java:573) at org.keycloak.services.resources.LoginActionsService.registerRequest(LoginActionsService.java:623) at org.keycloak.services.resources.LoginActionsService.registerPage(LoginActionsService.java:588) 22:42:11,860 WARN [org.keycloak.events] (default task-1) type=REGISTER_ERROR, realmId=chassi, clientId=chassi-web-app, userId=null, ipAddress=10.0.2.2, error=invalid_user_credentials, auth_method=openid-connect, auth_type=code, redirect_uri= http://localhost:3000/, code_id=c926d684-2a6b-4fb5-adb4-9df7de9d8483
