ERROR: The Compose file docker-compose.yml is invalid

version: '3.7'
services:
  docker-mongo:
   image:
     - mongo:4.2.1
   ports:
     - "27017:27017"
   networks:
     - mynetwork


networks:
  mynetwork:

When I execute docker-compose config I got the following error:

Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

So according to the error message I tried with version 2.2 and 3.3 both results in the same error message 

ERROR: The Compose file './docker-compose.yml' is invalid because:
services.docker-mongo.image contains an invalid type, it should be a string

  docker-mongo:
   image: mongo:4.2.1
   ports:
     - "27017:27017"
   networks:
