BUG: ip_address and user_agent should be in a single identifiers object. Error: At least one user identifier must be provided

[amerkay]

Describe the bug
Error response from X: At least one user identifier must be provided.

Why it's happening: The ip_address and user_agent are placed at the conversion object level rather than combined identifier following the X docs.

See X Docs: https://developer.x.com/en/docs/x-ads-api/measurement/web-conversions/api-reference/conversions

From Docs:

IP address is required to be passed in conjunction with another identifier (twclid, email address, phone number or user agent).

User Agent is required to be passed in conjunction with another identifier (twclid, email address, phone number or IP address).

{
  "conversions":[
     {
        ...
        "identifiers":[
           {
              "ip_address":"1.0.0.0",
              "user_agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36"
           }
        ],
        ...
     }
  ]
}

To Reproduce
When I send ip_address and user_agent properties, this happens.

                        },
                        {

                        }
                    ]
                }
            ]
        },
        "JSON_ARRAY": {},
        "XML": {},

}

Error response from Twitter:

{
  "response": "{\"errors\":[{\"code\":\"INVALID_PARAMETER\",\"message\":\"At least one user identifier must be provided\",\"parameter\":\"\"}],\"request\":{\"params\":{\"account_id\":\"18ce55453yk\"}}}",

  "content-type": "application/json; charset=utf-8",
  "routerSubStage": "router_dest_delivery",
  "payloadStage": "router_input"
}

Expected behavior
ip_address and user_agent should be in a single object, not two separate ones:
{
"ip_address":"1.0.0.0",
"user_agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36"
}
