How do I convert an object to a string for the header? rhai script for router.

```auto
let subGraphHeaders = #{
        loginName: loginName,
       isPrimary: sPrimary
    };
request.subgraph.headers["user"] = json::stringify(subGraphHeaders); // something like this

```

When I do it this way, it works, but I need to add more value from claims

```auto
request.subgraph.headers["user"] = `{"loginName":"${loginName}", "isPrimary":${isPrimary}}`

```

Can you use `subGraphHeaders.to_json()`? This is a [Rhai feature](https://rhai.rs/book/ref/object-maps.html?highlight=to_json#built-in-functions), but I haven’t tested from within Router just yet
