Analytics API paging object ignoring pageNumber in Data Action

Dealing with a very strange bug here with the analytics paging object. it’s returning 1 for pageCount even when i’m setting pageSize to 500 and pageNumber to 2, which breaks the flow loop. here’s the payload hitting /api/v2/analytics/conversations/details/query:

{ "pageSize": 500, "pageNumber": 2 }

response still dumps page one so probably just missing a header but the docs don’t mention it.
