title: List call fails about 10 pages in
body: <p>I'm having some trouble with the "list" API call - it works OK for about 10 pages of results (feeding in the value of nextPageToken into subsequent calls), but then I get a 500 error (always at the same point). Is there a limit on the number of pages of results that can be listed?</p>
  
  <p>Also, just confirming - the discovery file has a maxResults parameter but it seems to have no effect - is this correct?</p>
  
  <p>Cheers,
  Miles</p>
