In the given example, json_path will yield [[17,50,19,0],"87c7b863-4be0-4324-ab84-dfde19bccc18",[17,50,19,0],"12ad915b-781e-4859-aedb-2d1e51f9d384"]. Can this be easily handled subsequently?

[chawyehsu]

The output will be handled by the specified regex next to the jsonpath, so it's up to the manifest author. I believe it'd help to write simpler regex by yielding such clean json output.
