envoy configuration parsing error INVALID_ARGUMENT:Unexpected token

Question

Im trying to setup a basic envoy proxy (using Docker) from the envoy documentations but I keep getting parsing error as below:

As you can see it is JSON to Proto parsing error however I don't know where I have devated from the docs on the website. Unless the docs are out of date! Below is my envoy.yml file:

admin:
  access_log_path: /tmp/admin_access.log

    socket_address: { address: 127.0.0.1, port_value: 9901 }

              domains: ["*"]
              routes:
              - match: { prefix: "/" }
                route: { cluster: some_service }
          http_filters:

                address: 127.0.0.1
                port_value: 1234

And this is the envoy part of my docker-compose file:

 envoy:
    image: envoyproxy/envoy:v1.11.1
    command: /usr/local/bin/envoy -c /etc/envoy/envoy.yml -l debug --service-cluster proxy
    container_name: envoy
    ports:
      - 8070:12000
    volumes:
      - ./scripts/envoy/envoy.yml:/etc/envoy/envoy.yml
    networks:
      - mongo-cluster

Found the problem, I was being silly, I knew I must being silly but couldn't figure it out till I posted the question lol.

The problem was to do with my yaml file extension name. Instead of .YAML I was using .YML I don't know why VS Code recognized the extension which put me off.
