I am using Helix Ultimate 2.0.4 on Joomla 4.0.2 and want to use the Joomla 4 Web Service API. When I send a GET request to {{base_path}}/api/index.php/v1/banners/categories the response is:

{"errors":[{"code":500,"title":"Internal server error"}]}

When I deactivate the System - Helix Ultimate Framework Plugin the Web Service is working and the response is as expected:

{
    "links": {
        "self": "{{base_path}}/api/index.php/v1/banners/categories"
    },
    "data": [
        {
            "type": "categories",
            "id": "3",
            "attributes": {
                "id": 3,
                "title": "Uncategorised",
                "alias": "uncategorised",
                "note": "",
                "published": 1,
                "access": 1,
                "checked_out": null,
                "checked_out_time": null,
                "created_user_id": 53,
                "parent_id": 1,
                "level": 1,
                "lft": 3,
                "rgt": 4,
                "language": "*",
                "language_title": null,
                "language_image": null,
                "editor": null,
                "access_level": "Public",
                "author_name": "Super User",
                "count_trashed": 0,
                "count_unpublished": 0,
                "count_published": 0,
                "count_archived": 0
            }
        }
    ],
    "meta": {
        "total-pages": 1
    }
}

Is there a way to use the Joomla 4 Web Service API with activated System - Helix Ultimate Framework Plugin?
