graphql middleware auth don't worked.

Hi, I have a problem with the connection authorization after you connect the easygraphql-format-error.
The problem is that, I give information about authorization in req due to the fact that I connected the plugin in context, it stopped being defined.

isAuth.js:

const jwt = require("jsonwebtoken");

module.exports = (req, res, next) => {
  const authHeader = req.get("Authorization");
  if (!authHeader) {
    req.isAuth = false;
    return next();
  }
  const token = authHeader.split(" ")[1];
  if (!token || token === "") {
    req.isAuth = false;
    return next();
  }
  let decodedToken;
  try {
    decodedToken = jwt.verify(token, "somesupersecretkey");
  } catch (err) {
    req.isAuth = false;
    return next();
  }
  if (!decodedToken) {
    req.isAuth = false;
    return next();
  }
  req.isAuth = true;
  req.userId = decodedToken.userId;
  next();
};

app.js:

app.use(isAuth);

app.use("/", (req, res) => {
  console.log("req", req),
    graphqlHttp({
      schema: schema,
      rootValue: graphQlResolvers,
      graphiql: true,
      context: { errorName },
      formatError: err => {
        return formatError.getError(err);
      }
    })(req, res);
});

I apologize in advance for my English...
I solved this problem like this:
context: { errorName, isAuth: req.isAuth, userId: req.userId }

Perhaps someone has a better solution? Advance thanks.
