I've got a Data Stream setup for access to an external REST API call and am having trouble getting information from the response body.
I can successfully get it load test data and to load the first page of data. I have defined the path in the Splitter step as "$.results" and it returns valid data just fine for the actual content. I'm having problem with the pagination.
The values that I need are returned in the response_body.
I've defined my pagination variables:
I've defined them all to get the next value from "Script".
When I run it as a test, I see that the response_body contains a valid entry for the page and that if I stick the response_body in a JSON formatter, is see the content as valid: there's three "header" fields and the results array.
I know that page_Response is an object and the actual response_body is a JSON formatted objec But I can't seem to get any value returned for either count or next or previous from the response body into a local variable or the variables object.
How do I specify that I want to select the response_body from the page_Response and treat is as a JSON object to be parsed, so that I can stringify item and get the page number out of it.
I suspect it's something silly, but I've looked at it everyway from Sunday.
As always, any help is very much appreciated. Scot.
Any help would be greatly appreciated.

Hi Scot,
I'm not positive that I'm understanding you correctly but wanted to chime in in case.
Are you setting the getNextPage variable in the Pagination Variables Script?
In the Pagination Variables Script you'll want to update the getNextPage variable to true or false based on the "next" variable from the response body. If set to true, the stream will continue and call the next page.
