Missing user_id from event.user in Post-Registration Action

according to the docs there should be a user_id property in event.user
and that’s the case in an existing tenant
but I now opened a new tenant and tried to access this property again
but I get an error

`Property 'user_id' does not exist on type '{ username?: string | undefined; email?: string | undefined; app_metadata?: AppMetadata0 | undefined; user_metadata?: UserMetadata0 | undefined; name?: string | undefined; ... 4 more ...; picture?: string | undefined; }' `

also in the older tenant, the type of user is Types.User
