Hi @daniel.ekbom

Welcome to the Auth0 Community!

One of the user had a similar problem and solved it with the usage of Management API with `getUser({ id: user.user_id })`

> **[Retrieve Users with the Get Users Endpoint](https://auth0.com/docs/manage-users/user-search/retrieve-users-with-get-users-endpoint)**
>
> Learn how to retrieve lists of users using the get\_users endpoint.

> [@Add the upn to event.user](https://community.auth0.com/t/add-the-upn-to-event-user/60839/4):
>
> I was able to get the upn field by using getUser({ id: user.user\_id }) from using the management api: [https://auth0.github.io/node-auth0/module-management.ManagementClient.html#getUser](https://auth0.github.io/node-auth0/module-management.ManagementClient.html#getUser)

Thanks  
Dawid
