DigitalSide Taxii 2.1 Requests with the next parameter

[annoyingapt]

Hi there, just a quick question regarding making requests to the DigitalSide Taxii server, I might doing something silly, but I seem to be running into an issue trying to use the next parameter when trying to use pagination.

If I go to the URL:
https://osint.digitalside.it/taxii2reports/collections/e98d6c94-fbce-11ed-b5dd-3bad2ffe9ebf/objects/?limit=1
I get the following response back..

{
    "more": true,
    "next": "5c8f4047-a1b1-4e33-bca4-1a03254f35ea",
    "objects": [
        {
            "contact_information": "[email protected]",
            "created": "2018-09-23T12:10:00.000Z",
            "description": "DigitalSide Threat-Intel - Just another OSINT hub",
            "external_references": [
                {
                    "description": "DigitalSide Threat-Intel Repository",
                    "source_name": "website",
                    "url": "https://osint.digitalside.it"
                }
            ],
            "id": "identity--9fa9e87c-4c07-4376-96b1-7dbe0ba5b8a6",
            "identity_class": "organization",
            "modified": "2022-09-23T12:10:00.000Z",
            "name": "DIGITALSIDE.IT",
            "spec_version": "2.1",
            "type": "identity"
        }
    ]
}

If I then add the next value to the URL:
https://osint.digitalside.it/taxii2reports/collections/e98d6c94-fbce-11ed-b5dd-3bad2ffe9ebf/objects/?limit=1&next=5c8f4047-a1b1-4e33-bca4-1a03254f35ea
I get the following response back..

{
    "description": "The server did not understand the request or filter parameters: 'next' not valid.",
    "http_status": "400",
    "title": "ProcessingError"
}

Am I doing something silly? Any help would be appreciated.
