Building a GRPC Service Using Core Routines?

I made a broken apartment 20 lessons. And it was basically one every other week so that people have the opportunity to adjust the material. I remember helping someone to make build an isolated service using a framework like ProPro Plus and commonly used by, you know, a lot of people. So my expertise is in building GRPC services and implementing them using core routine. The main pitfall that people encounter with coroutines is testing which they seem to grasp pretty well.
