I dont know if i do something wrong but In my website Usync dont save the relations for each relationsTypes. I need it for all my custom relations. here the config i set :

  "Sets": {
    "Default": {
      "Handlers": {
        "RelationTypeHandler": {
          "Enabled": true,
          "Settings": {
            "Exclude": "s",
            "IncludeRelations": "true"
          }
        }
      }
    }
  }

Thks in advance !
