Issue running grpc-dynamic-gateway

I am having some issues using grpc-dynamic-gateway, and I was hoping to get some ideas or help from you on getting things working (or tell me if I’m doing something wrong).

My own proto file is failing, but I tried to run it against the example/api.proto file in the repository, and I am getting the same service.children error, as ‘children’ on the service instance seems to be undefined.

C:\ grpc-dynamic-gateway-master>node example example/api.proto 5050 ./example/api.js
C:\grpc-dynamic-gateway-master\example\index.js:35
      **proto[p][t].service.children.forEach(c => {**
                                  ^
 
**TypeError: Cannot read property 'forEach' of undefined**

A few questions:

1. Do you know why I would get an error like that?
2. You have a an empty stubbed out annotations.proto file with your test.proto a. Why is it stubbed instead of the one from grpc-gateway? b. With the stub, the http options attribute wouldn’t parse it seems, or am I missing something?
3. The install docs for grpc-dynamic-gateway says to do this: a. npm -g grpc-dynamic-gateway b. I presume it’s a typo and it should be npm install?

Thank you, Graham

Sorry for taking so long to get back to this; grpc-dynamic-gateway seems to work now after your changes. Thank you!

Maybe try just running on the console something like this:

grpc-client run --host localhost:50051 -I ./proto helloworld.proto -m hellowor
ld.Greeter.SayHello -a '{"name": "World"}'

after you do npm i -g grpcnode to get grpc-client in your path.
