nestcloud-grpc-example's Issues

Demo not working

I get this error when testing out this demo, I think it might be an issue with nestcloud-grpc

[ExceptionHandler] metatype is not a constructor

when i import
ConsulServiceModule.register({dependencies: [NEST_BOOT],}),
LoadbalanceModule.register({ dependencies: [NEST_BOOT], }),

inside the app module

Error: connect ECONNREFUSED 127.0.0.1:8500

When I run yarn start:server1 or yarn start:server2,both I got following error message:

[Nest] 4552   - 2020-12-18 16:57:12   [ConsulService] Unable to initial ServiceModule, retrying... +6015ms
Error: connect ECONNREFUSED 127.0.0.1:8500

Did I miss something?
I'm not familiar with Consul or gRpc
I just start up the 2 server with scripts in package.json directly
