Post User Registration user does not have user.name property

My use case: when a user is registered in Auth0, depending on a field in their app_metadata, I make an API call to Databricks to provision a user. The created used in Databricks kept getting their email as their name. This is how I encountered the issue.

Despite having

name: Foo Bar

in their user_metadata after user creation, the event in the hook never had the value. It did have familyName and givenName so I just used that.

To solve, I post to Databricks using

    "name" : {
      "familyName": familyName,
      "givenName": givenName
    }

but I couldn’t figure out why name wasn’t in the event object.
