I was reading the documentation and it does not work as the code indicate. it raise and error not finding a file "models/object_type" However running the CURL command it works perfectly. https://developers.hubspot.com/docs/api/crm/associations I've tested with versions 17.1 and 17.2 ```rb # this code fails require 'hubspot-api-client' api_client = Hubspot::Client.new(access_token: 'YOUR_ACCESS_TOKEN') api_response = api_client.crm.objects.basic_api.create(object_type: "deals", object_id: "DEAL_ID", to_object_type: "contacts", to_object_id: "CONTACT_ID", association_spec: [{"associationCategory":"USER_DEFINED","associationTypeId":ASSOCIATION_ID}]) ``` ``` # This command works curl --request PUT \ --url https://api.hubapi.com/crm/v4/objects/deals/DEAL_ID/associations/contacts/CONTACT_ID \ --header 'authorization: Bearer YOUR_ACCESS_TOKEN' \ --header 'content-type: application/json' \ --data '[ { "associationCategory": "USER_DEFINED", "associationTypeId": ASSOCIATION_ID } ]' ````
