mountebank-grpc:imposter load - failed @ protobufjs/src/root.js about mountebank-grpc

Hi @mukrisp ,

I see the problem. I'll comment on a few things though since it looks like you're trying to get this to work 😄.

1. You mentioned that you put in a print statement and it caused mountebank to crash. I believe it's by design. From the http protocol it looks like you're supposed to print a JSON object to the console so mountebank knows the service loaded successfully. If you were using console.log(...) to print something before that, I could see a crash happening.

2. The error you're seeing is due to my bad documentation. If you remove the comment under _note: ... under services, the protocol/service should load. When testing this I sent this body to the imposters endpoint via postman:

{
    "protocol": "grpc",
    "port": 4545,
    "loglevel": "debug",
    "recordRequests": true,
    "services": {
        "example.ExampleService": {
            "file": "example.proto"
        }
    },
    "options": {
        "protobufjs": {
            "_note": "any options to protobufjs",
            "includeDirs": ["/mountebank-grpc/src/protos"]
        }
    },
...
}

That property was accidentally being sent to root.js.

3. You should be able to send a client request to UnaryUnary after that. If you're using the JSON from the doc, you'll want to remove the stubs.responses[0].is.error since that will override the response in value.

Let me know if you have any other problems. There are some limitations with this implementation with the WellKnownTypes, but if you don't need those these are good for a quick mock.

Hi,

Thanks for looking into this. As per your suggestion updated the imposter config by excluding the "_note" param.
It worked. Thanks again.
I am exploring on this. Will post here if any info is needed.
