--------------------------------------
Hi [~dstiegli1] . I came back to this and retested it. Looks like I made an
error on the actual behavior I'm seeing with the *Transform Result Filter.*
Seems like this filter does not apply to the root object, but more so to the
keys inside the root.
Ultimately, what I was trying to achieve is removing *null* lines when using
the JSON Lines settings and filtering out a line by setting it to null. I'm
attaching a test flow I created. As you can see, the resulting transform has
null lines which I am unable to filter out. Perhaps the scope of the ticket
would change in this case then

> JSLT Transform with JSON Lines should perform 'Transform Result Filter' per
