    // with an empty `ns=` Consul will use the namespace that is assigned to
    // the token, and when we get the response we can pick that back off the
    // responses `Namespace` property. As we don't receive a `Namespace`
    // property here, we have to figure this out ourselves. But we also want

    // template engineer'. This feels like the best place/way to do it as we
    // are already in a asynchronous method, and we avoid adding extra 'just
    // for us' parameters to the query object. There is a chance that as we
    // are discovering the tokens default namespace on the frontend and
    // assigning that to the ns query param, the token default namespace 'may'
    // have changed by the time the request hits the backend. As this is
