It looks like CheckBulk requires the resource's

object_id

rs
CheckBulkPermissionsRequestItem {
    resource: Some(
        ObjectReference {
            object_type: "page",
            object_id: "", //<<<<<<< this is required but I cannot provided(it is also what I am finding out too)
        },
    ),
    permission: "viewer",
    subject: Some(
        SubjectReference {
            object: Some(
                ObjectReference {
                    object_type: "usergroup",
                    object_id: "1",
                },
            ),
            optional_relation: "",
        },
    ),
    context: None,
}

called `Result::unwrap()` on an `Err` value: status: InvalidArgument, message: "invalid CheckBulkPermissionsRequest.Items[0]: embedded message failed validation | caused by: invalid CheckBulkPermissionsRequestItem.Resource: embedded message failed validation | caused by: invalid ObjectReference.ObjectId: value does not match regex pattern \"^(([a-zA-Z0-9/_|\\\\-=+]{1,})|\\\\*)$\"; invalid CheckBulkPermissionsRequest.Items[1]: embedded message failed validation | caused by: invalid CheckBulkPermissionsRequestItem.Resource: embedded message failed validation | caused by: invalid ObjectReference.ObjectId: value does not match regex pattern \"^(([a-zA-Z0-9/_|\\\\-=+]{1,})|\\\\*)$\"", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc", "io.spicedb.respmeta.requestid": "d2lqu8eih8mhe3h22vlg"} }

The question I need to answer is What pages does usergrup 1 has access to and thus the pages is what I am finding out and I cannot provide.
