        "attributes": {},
        "id": "79505248",
        "relationships": {
            "memberships": {
                "data": []
            }
        },
        "type": "user"
    },
    "links": {
        "self": "https://www.patreon.com/api/oauth2/v2/user/79505248"

If this is your creator user, you wont get any memberships if you dont have one and you are using the creator access token. If this is another user, make sure that your token has the memberships scope.
