Andrei_Y - can you download the actual output and mask the base url so I have a better idea of the actual output produced and where it gets into infinite looping?

To break the infinite loop, you can always use something like the following in the Has Next property:

$snap.out.totalCount < 10

I cannot use 

$snap.out.totalCount

because I don't know how many pages I need to fetch and it depends on how many a Facebook page contains posts. I attached a file with response from Facebook Graph API where I replaced unique strings with <---111--->, <---222-->, <---333--->, <---444--> and hid data with <---hidden--->. Facebook support ignores the issue. The _debug contains requestLine in HTTP Client which I might use but it is not available in the Pagination section.
