Zoho CRM JS Widget User Reporting To returns "null"

Zoho CRM JS Widget User Reporting To returns "null"

In Zoho CRM JS Widgets, the get users API shows the following:

I would expect "Reporting_To" to show the user they report to based off the hierarchy in the roles. Is there any other way using APIs to find out who a user reports to? 

End goal is to create a dashboard widget that shows a user's team based on who is logged in and specific goals for each team member from their user profile. I'm able to do basically everything except dynamically update a user's team based off of role name if a new role is added/removed. Each time I'm having to manually add the new role name in the widget and reupload. 

Any ideas?
