Solution

The reason for this error is that the YML format is incorrect. The YML format defined by Google is too strict. Every colon must be followed by a space

Original format:

version:"3"
services:
  web:   
    image: licerlee/friendlyhello:v1
    deploy:
      replicas:5
      resources:
        limits:
          cpus:"0.1"
          memory:50M
      restart_policy:
        condition: on-failure
    ports:
      - "80:80"
    networks:
      - webnet
networks:
  webnet:

Change to:

version: "3"
services:
  web:
   
    image: licerlee/friendlyhello:v1
    deploy:
      replicas: 5
      resources:
        limits:
          cpus: "0.1"
          memory: 50M
      restart_policy:
        condition: on-failure
    ports:
      - "80:80"
