writing some script in sourceQuery in DHF flow of Marklogic

[yamado3856]

I have one requirement while running DHF flow I can't use cts.uris in place of sourceQuery. I want to use some script. How can I achieve this ??
I tried like this.. but not working
I have placed my script under custom directory. and calling that script in flow. If I run sourceQuery in qconsole it was working. but if I try to run the flow getting error.
