Services is called twice when started

[1fabiopereira]

Current Behavior

I was doing some tests on my services and noticed that the service is started 2 times and it seems to me the second instance replaces the first one, I put a console.log in the class constructor and it was fired 2 times.

Expected Behavior

The expected behavior was that the class's constructor was called only once, which is more strange is that if you have to add other parameters to the constructor (DI) the first time the constructor is called the additional parameters are undefined and only exist on the second call .

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

Create a service using TS and classes;
Put a console.log inside the constructor;
Export the class with a function decorator;

Reproduce code snippet

import { Context, Service as MoleculerService, ServiceBroker } from 'moleculer'
import { Action, Service } from 'moleculer-decorators'
import { verify, sign } from 'jsonwebtoken'

import { IAuth } from '@Interfaces'
import { TimeInSeconds } from '../../src/helpers/enums/time'

@Service({ name: 'Auth' })
class AuthService extends MoleculerService {
  public constructor(broker: ServiceBroker) {
    super(broker)
    console.log('Called At: ', new Date())
  }

  @Action({
    cache: {
      enabled: true,
      ttl: TimeInSeconds.FiveMinutes,
    },
    params: {
      token: 'string'
    }
  })
  public async DecodeJWT(ctx: Context<{token: string}>): Promise<IAuth.JwtPayload | string | null> {
    try {
      return verify(ctx.params.token, process.env.JWT_SECRET)
    } catch (error) {
      return null
    }
  }

  @Action({
    params: {
      id: 'string',
      email: { type: 'string', optional: true },
      name: 'string'
    }
  })
  public async GenerateJWT(ctx: Context<IAuth.JwtDto>): Promise<string | null> {
    try {
      const { id, email, name } = ctx.params
      return sign({id, email, name}, process.env.JWT_SECRET)
    } catch (error) {
      return null
    }
  }
}

export default (broker: ServiceBroker): MoleculerService => new AuthService(broker)
