Is there a way to selectively exclude fields output from a mapper snap?

I have a case where many fields may have to be excluded from mapper output, as if they never existed, selectively during a run. I am going to a cloud instance of a routine that will take null values...

You need to put $ in the target path so that the result of the cleanupTree() function is used as the new output value. The ‘Pass Through’ option should also be unchecked. Without $ in the target path, lib.objutil.cleanupTree($) is treated as the JSON-Path to delete.

THANKS, that did it! I thought I had tried the “$” as well, but it works now. THANKS!

    Did anything happen to cause this to break? It doesn’t seem to work anymore.
