Proccess is not declared

Hello. I am trying to assign a process variable to an application variable, and I am encountering this error.

@RS_App ,

Have you added process into apps? Until you add you can’t see the process method.

Thanks,
Arvind

Sure, everything worked perfectly yesterday, but the error appeared today.

@RS_App ,

Please remove your process and readd again and test it…

Did you made any change into in out argument in process?
