@Raghad

Usually this will happen when you are not passing arguments correctly

Check all arguments are passing correctly between the flows

Hope this helps you

Thanks

There are no arguments. This is my workflow, just printing “Hello”

@Raghad

Reinstall studio and try again, this happens before for some users also, so there was some issue with the license of the UiPath studio

You can uninstall studio, restart the system, and install the studio

Try to connect to orchestrator once done

Hope this helps you

Thanks

Thanks it worked!
