User_email field is coming up empty in the '/report/meetings/{meetingId}/participants' API response

We use the Zoom Meeting SDK to have a user join the meeting, we are passing the userEmail field in the SDK.

But when we call the ‘/report/meetings/{meetingId}/participants’ API the user_email field comes up empty.

Only the user_email for the host is populated correctly, we do receive the name of the user.

Because of this we are not able to map the users internally. Please help.
