I have configured Role-Strategy using JCasC plugin see configuration and the end.
But now following error occurs when updating manually

When I add a new user manually I will get following error:
 
I have a workaround for this, see beneath this stack trace and configuration

WORKAROUND:
Hi Jenkins JCasC-Plugin and Role-Strategy-Plugin teams,
 
I found a work around for this issue.
Initially when Jenkins has started I go to "role-strategy/manage-roles"
http://localhost/role-strategy/manage-roles
 
and then just click "Save" button
After this "save" I can make changes to http://localhost/role-strategy/assign-roles without errors
 
Now I'm trying to find out how to make a groovy script to implement this workaround
 
I tried the following code but that didn't work
      def currentAuthenticationStrategy = Jenkins.instance.getAuthorizationStrategy()
      Jenkins.instance.setAuthorizationStrategy(currentAuthenticationStrategy)
      Jenkins.instance.save()
 
I hope you can support me here.
 
thanx
 
kind regards,
Bas
