Hi @Abduerhman Salama 

If you're debugging strongly connected Server Actions from the CS module you need to select the consuming module as the entry point and start the debug session such that the breakpoint entry comes from consumer to producer.

Suppose you're debugging loosely connected actions like REST API calls, Service Actions, or Asynchronous Processes or Timers you don't need to select the entry module. You can just add the breakpoint and then start the debug session.

I hope this helps!
