@Casandra_Villagra - welcome to the forum! I think you can ignore the assignee_status. There’s an old thread about it being deprecated here, but it was supposed to stop getting returned when calling that endpoint so not sure why it’s showing (confirmed in my testing too, don’t recall seeing it when I called this endpoint recently…).
As for your question about assignee, could you post a code snip of your actual calls? I see the assignee as expected when I call it. assignee does get returned as an object, so I’m not sure if you need to do anything to interpret that in Zapier (I have used Make before and this was no issue, so I assume the same is true in Zapier).
