How to register schema in mesher to make intercalls from other microservices.

I have java chassis SDK based `serviceA` talks to mesher acting as sidecar proxy for the python based `serviceB`.
When I call serviceB operations via mesher with restclient like this

```
RestTemplate restTemplate = RestTemplateBuilder.create();
String result =
restTemplate.getForObject("cse://testApp:serviceB/shippingservice/bmi?height={height}&weight={weight}"
, null, String.class,request.getHeight(),request.getWeight());

```
I am always ended up in `Message Not Found` Error.
```
{
"message": "Not Found"
}
```

Relevant logs
```
2023-03-02 13:12:31.428 INFO 1206 --- [oup0-1-thread-1] o.a.s.registry.swagger.SwaggerLoader : try to load schema locally, appId=[testApp], serviceName=[serviceB], schemaId=[shippingservice]
2023-03-02 13:12:31.444 WARN 1206 --- [oup0-1-thread-1] o.a.s.registry.swagger.SwaggerLoader : no schema in local, and can not get schema from service center, appId=Elavon, microserviceName=shippingservice, version=1.1.1, serviceId=387916b7066a225101afb347c009988e1a78ea67, schemaId=shippingservice.

```

Then I realised that mesher would not know about the schema/operations supported by the sidecar main `serviceB` which it proxies.

So the question is how to register the schema in mesher with the operations supported in the microservice in `serviceB`
I have tried creating schema `yaml` file and put it under `mesher/conf` folder. But it does not work. The schemas are not getting uploaded or registered in the service center.

Please suggest how to make intercommunication calls from serviceA to serviceB through mesher?
