Grpc source not getting schema

[SonofNun15]

I have a GRPC service that has reflection enabled.

I am able to enumerate the schema via reflection in postman and make requests to this service.

I set up my mesh config like this (same port as postman uses):

sources:
  - name: People
    handler:
      grpc:
        endpoint: localhost:5059
        useHTTPS: true

The service is setup to use HTTPS and postman is connecting via TLS.

When I run the mesh service via mesh dev, it runs successfully and brings up the graphql tools, but there is no schema generated. If I look at the schema.graphql files in the .mesh folder and try to open any of the exploration tools in the graphql tools, everything is completely empty.

Any ideas as to what I am doing wrong? Is there something extra you have to do to get reflection to work properly?

UPDATE:

Tried pulling in the proto file locally to see what the issue was and I'm seeing this in the console:

Configuration is not valid:
data/sources/0/handler/grpc must NOT have additional properties

UPDATE:

Here's the proto file I'm using. Maybe it's not compatible for some reason, possible because of the datetime fields?

syntax = "proto3";

package person;

import "google/protobuf/timestamp.proto";

option csharp_namespace = "Models.Person";

service People {
	rpc List (PeopleRequest) returns (PersonListReply);
	rpc Get(PersonRequest) returns (Person);
	rpc Phones(PhonesRequest) returns (PhonesReply);
}

message PeopleRequest {
	int32 limit = 1;
	int32 page = 2;
	oneof optional_query {
		string query = 3;
	}
}

message Person {
	string id = 1;
	string name = 2;
	string email = 3;
	google.protobuf.Timestamp date_of_birth = 4;
}

message PersonListReply {
	int32 count = 1;
	repeated Person people = 2;
	int32 page_size = 3;
}

message PersonRequest {
	string person_id = 1;
}

message PhonesRequest {
	string person_id = 1;
}

enum PhoneType {
	PRIMARY = 0;
	HOME = 1;
	WORK = 2;
	MOBILE = 3;
	OTHER = 4;
}

message PhonesReply {
	string id = 1;
	string person_id = 2;
	string number = 3;
	PhoneType type = 4;
}

OK, first issue was the versions of @graphql-mesh. I updated everything to the latest versions and got closer.

Next, it seems like there's a bug where reflection isn't used if the source parameter is missing. You have to specify this in .meshrc to use reflection:

grpc:
  endpoint: localhost:5059
  source: { file: "" }
  useHTTPS: true

Finally, it seems like the connections under the covers don't like using a self signed dev cert. Looking into how I can turn off the cert validation during local development.

Can get around the self signed dev cert by setting NODE_TLS_REJECT_UNAUTHORIZED=0 environment variable when running mesh / node. Obviously be careful when doing this in your environment as it could enable unsafe connections from node.
