Calling start() on grpc client throws DeprecationWarning after @grpc/grpc-js v1.10.0

[deekthesqueak]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

When using a grpc based microservice with @grpc/grpc-js v1.10.0 or greater will cause a DeprecationWarning to be thrown when start() is called.

The @grpc/grpc-js package was updated from v1.9.14 to v1.10.0 with release v10.3.2 via PR #13173

https://github.com/grpc/grpc-node/blob/9886ee2da71ead90f61fb0d6688abb56525a60fd/packages/grpc-js/src/server.ts#L981-L984

(node:30234) DeprecationWarning: Calling start() is no longer necessary. It can be safely omitted.

Minimum reproduction code

https://github.com/nestjs/nest/blob/v10.3.8/sample/04-grpc

Steps to reproduce

1. cd nest/sample/04-grpc
2. npm install
3. update src/grpc-client.options.ts to contain

import { ClientOptions, Transport } from '@nestjs/microservices';
import { join } from 'path';

export const grpcClientOptions: ClientOptions = {
  transport: Transport.GRPC,
  options: {
    package: 'hero',
    protoPath: join(__dirname, './hero/hero.proto')
  },
};

4. npm run start:dev
5. Observe startup and error

Expected behavior

When using @grpc/grpc-js v1.10.0 or greater with nestjs v10.3.2 or greater no DeprecationWarning is thrown
