JSLT attribute with empty array is not rendered in the transformed content

[dharriso]

We are transforming this a JSON object and as part of a larger JSLT we have this attribute that has an empty array i.e. "recharge-non-monetary-amounts": [ ],.
The generated output looks good apart from the fact that the ""recharge-non-monetary-amounts": [ ]" is not present.

However if I make the array contain a value then attribute is rendgeneartedred i.e. change to "recharge-non-monetary-amounts": [null]. I can see it

{
"recharge-non-monetary-amounts" : [ null ]
}

Is there an optimisation that removes the attribute because the array is empty? Any suggestions

This is filtered out by what's called the "object filter". You can set it in the API https://github.com/schibsted/jslt/blob/master/docs/api.md
