zato.simpleio.SerialisationError: Required element `id` missing in `{}`

Hi Everyone,

I am a new beginner in Zato. I am using Zato with docker with the following files
docker-compose.yml

version: "3"

services:
  zato:
    image: ghcr.io/zatosource/zato-3.2-quickstart
    container_name: zato
    ports:
      - "8183:8183"
      - "8083:11223"
      - "17010:17010"
    environment:
      Zato_Dashboard_Password: "steve"
    volumes:
      - ./libs/requirements.txt:/opt/hot-deploy/python-reqs/requirements.txt
      - ./libs:/opt/libs

I have created a basic service using Hot-deploying your first service. The code is the following

from zato.server.service import Service

class GetUserDetails(Service):
    """ Returns details of a user by the person's ID.
    """
    name = 'api.user.get-details'

    def handle(self):

        # For now, return static data only
        self.response.payload = {
            'id': "111",
            'user_name': 'John Doe',
            'user_type': 'SRT'
        }

When I deploy my service via Web-admin interface, I have the following on my docker container logs

I don’t know what I have done wrong. It was just a simple copy-paste
If you could help me guyz I would be really grateful

My second question is, that could we use this docker-compose for production. Do you have any suggestion please.

Thank you very much :grinning: :grinning:

Hello @louistwiice,

please use the latest Quickstart image that was published today - it corrects the very situation that you reported.

As to the usage of this image in production, yes, definitely, you can use it in any environment.

Regards.
