| # Description | |
| This example demonstrates basic RPC error handling in gRPC. | |
| # Run the sample code | |
| Run the server, which returns an error if the RPC request's `Name` field is | |
| empty. | |
| ```sh | |
| $ go run ./server/main.go | |
| ``` | |
| Then run the client in another terminal, which does two requests: one with an | |
| empty Name field and one with it populated with the current username provided by | |
| os/user. | |
| ```sh | |
| $ go run ./client/main.go | |
| ``` | |
| It should print the status codes it received from the server. |
