I am getting error while implementing JSON Path filter in POST RR pair. Suggest how to resolve this issue??
It looks like you're hitting "Run Filter" with no JSON document loaded at runtime.
Try clicking the button "Replay model to a specific point" (it's two buttons to the right of the ITR button). Select the step you have the filter on, and let the test case run. Now, you should have a sample JSON document to work with, and the "Run Filter" button will work.
