I am using the grails-audit-pluggin verion 4.0.1 in my grails 4 application with grails shiro 4.3 plugin and getting below
Error:

I have created the ShiroAuditResolver class in src/main/groovy folder.

@Component('auditRequestResolver')
class ShiroAuditResolver extends DefaultAuditRequestResolver {
    @Override
    String getCurrentActor() {
        SecurityUtils.getSubject()?.getPrincipal()
    }
}

and registered in resources.groovy:

// Place your Spring DSL code here
beans = {
    auditRequestResolver(ShiroAuditResolver) { }
}

Now in the getCurrentActor() if instead of SecurityUtils.getSubject()?.getPrincipal() if I replace with a hard coded String it doesn't give me any error.
Please suggest if there is anything wrong here.

Can you provide an example project that reproduces the problem?
