Issue retrieving webinar registrants

[lyv-team]

Hello,
I have a small issue with the Zoom API. When retrieving the participants of a webinar, one of them does not have a “last_name” field. However, this field is required to join our meetings/webinars.
What’s even more confusing is that, when retrieving the participant list through your interfaces, the person does have a last name.
How is this possible?
