Empty Array input always renders empty object output no matter what the query is

[apoggi-carecloud]

Input:
[]
will always result in
Output:
{}
Example query:
{"hello": "world"}

@apoggi-carecloud Would http://try.jsonata.org/SycA90CIE describe your situation?
That looks like a bug to me, whereby the query which is being used to build a new output (and thus shouldn't care about the input) is being ignored in favour of processing of the input empty array. (Applying a function does work, so it's not outputting {} in every case)

Your linked example is exactly the issue I am having.

This issue is related to how JSONata handles input arrays. There is a lengthy discussion in #170 on this topic. I'm currently prototyping a solution that uses explicit syntax to determine whether to map over the input array verses just use it as a single context value.
