How to use gRPC with golang echo framework?

Question

I am trying to perform inter-service communication between microservices. I followed the documentation and it was successful. Then, I tried to establish the same with echo framework. But that gives me an invalid memory address when trying to call the gRPC registered method.

 rpc error: code = Unavailable desc = connection closedpanic: 
runtime error: invalid memory address or nil pointer dereference 
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x7eacad]

Server config:

    e := echo.New()
    e.Use(middleware.Logger())
    e.Use(middleware.Recover())
    e.Logger.Fatal(e.Start(":1323"))

    s := grpc.NewServer()
    hellopb.RegisterHelloServiceServer(s, NewServer())

    e.GET("/", func(c echo.Context) error {
        return c.JSON(http.StatusOK, echo.Map{"status": "success"})
    })
    s.Serve(e.Listener)

Client panics:

    resp, err := client.Hello(context.Background(), request)
    if err != nil {
        fmt.Printf("%+v", err)
    }

Hello is the function registered with gRPC.

please provide more details, like the panic stack or part of the code. This error does not look to be related to the framework. — rubens21, May 16 '21 at 15:33
Does it work fine if you replace the echo listener by a basic tcp listener (e.g. net.Listener) ? — rubens21, May 16 '21 at 19:09
In that case, http and gRPC server is not able to run on same port simultaneously. — RisingGeek, May 16 '21 at 20:09
yeah, I know. I was wondering if the `Echo` listener is affecting the gRPC communication. — rubens21, May 16 '21 at 21:47
