I am facing exactly the same issue. Using a NestJS gRPC microservice server as my source. This is how my proto file looks :

syntax= "proto3";

package auth;

service Auth {

    rpc Register(RegistrationDetails) returns (RegistrationResponse) { }
}

message RegistrationDetails {

    string name= 1;
    string email= 2;
    string phone= 3;
    string password= 4;
}

message RegistrationResponse {

    repeated string errors= 1;
}

@Archisman-Mridha @graphql-mesh/grpc version "0.24.26-alpha-20220831005710-aff7f7bc6" works for me

This is fixed in new version of @graphql-mesh/grpc@0.25.3. Closing issue.
