Retrieve user profile information using solid node client?

Thanks! I can successfully access my name. But the code you provided in Can not access node solid development server localhost returns “Can not read property value of null”
My code:

const { SolidNodeClient } = require("solid-node-client");
const client = new SolidNodeClient();
const $rdf = require("rdflib");
const store = $rdf.graph();
const fetcher = $rdf.fetcher(store,{fetch:client.fetch.bind(client)});
const FoaF = $rdf.Namespace('http://xmlns.com/foaf/0.1');
const VCARD = $rdf.Namespace("http://www.w3.org/2006/vcard/ns#");
const pim = $rdf.Namespace('http://www.w3.org/ns/pim/space#');
 
router.get("/loginSSI", async function (req, res) {
  console.log("done");
  try {
    console.log("try ");
    let ses = await client.login({
      idp: YOUR_IDENTITY_PROVIDER, // e.g. https://solidcommunity.net
      username: "username",
      password: "password",
    });
    console.log(ses.webId);
    const me = $rdf.sym(ses.webId);
    console.log("me: ", me);
 
    const profile = $rdf.sym(ses.webId).doc();
    console.log("profile: ", profile);
    await fetcher.load(profile);
    let myPrefs = store.any(me,pim("preferencesFile"));
    await fetcher.load(myPrefs);
    let mbox = store.any( me , FoaF('mbox'));
    console.log("mbox: ",mbox.value); // can not read property 'value' of null
    let token = uuidv4();
    req.session.token = token;
    req.session.save((err) => {
      auth.validTokens.push(token);
      res.redirect("/");
    });
    
  } catch (error) {
    console.log(error.message);
  }
});
