App Cloud Services

I am currently going through module 9 in the Mendix Rapid Developer set. I’m having a project security error regarding app cloud services. I’m not sure why this shows up or what app cloud service is. Any help on how to resolve this issue would be greatly appreciated.

Did you make sure to assign a security role to that module in your project security for a user role? so project security user role “user”  assign user role from AppCloudSecurity role
