I don’t have an API key for glidework to see an actual response. If you can capture a raw response for the /v1/jobs endpoint, using postman or curl, and post the JSON part here (preferably in a markdown codeblock) it might be possible to figure out why it isn’t working.
In the meantime, another guess is that the currentPage value could be starting at zero, so the expression for offset might need to be {{ ($response.body.currentPage + 1) * 100 }}
There is also this working example you could compare.
