Newtonsoft.Json.JsonSerializationException: Error converting value {null} to type 'System.Boolean'. Path 'users[0].marked_email_as_spam'

[dradovic]

For some old contacts (> 5 yrs), we get the following error when trying to list a user:

Intercom.Exceptions.IntercomException: An exception occurred while calling the endpoint. Method: GET, Url: https://api.intercom.io/, Resource: users, Sub-Resource:

I guess that marked_email_as_spam should be declared as a nullable boolean to support the loading of older contacts.

This is the call-stack:

Intercom.Exceptions.IntercomException: An exception occurred while calling the endpoint. Method: GET, Url: https://api.intercom.io/, Resource: users, Sub-Resource:
