Go: missing `omitempty` tag for optional arrays

[pastamoe]

If an optional field is of type array, quicktype doesn't add the omitempty tag

example schema:

schema.json

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string"
    },
    "name": {
      "type": "string"
    },
    "users": {
      "type": "array",
      "items": {
        "type": "string",
        "format": "uuid"
      }
    }
  },
  "required": ["id"]
}

generate code via quicktype -s schema --just-types -o types.go schema.json

types.go

type Types struct {
        ID    string   `json:"id"`            
        Name  *string  `json:"name,omitempty"`
        Users []string `json:"users"`         
}

The only required field is ID, so Name correctly gets the omitempty tag. But Users is missing it. Because of that, marshaling an instance of Types with a nil Users array will always generate an invalid json (i.e. won't pass validation with the above schema):

{
    "id":"",
    "users":null
}

The omitempty tag must be added for optional arrays also, so marshaling leaves them out.
