List registrants - missing next_page_token despite it should be

API Endpoint(s) and/or Zoom API Event(s)

Description
I send request to “getRegistrans” endpoint in my list I have above 5k registrants, in some situations I get only 500 (the numbers are different in each request) and there is no “next_page_token” in response despite it should be there cause I know that there is more pages. I’ve tried with different page size but the issue is still the same. I didn’t reveive any errors, response status code is always 200 only the token is missing. Recently I had about 30 events, and the problem occured only for a few of them

Error?
