$filter() with list containing null values resulting in Out of Index Exception.

[siddhantrawat]

while using $filter operation on list from an input, jsonata engine is throwing out of index exception due to null not being part of the element in the ArrayList. (size still being count of the, null + non Null, elements )

{
    "jsonataExpression": "$filter($, function($v, $i, $a){$v})",
    "inputJson": [
        1, null, 2
    ]
}

while if i use the data directly in jsonata, it works fine. like ->

{
    "jsonataExpression": "$filter([1,null,2], function($v, $i, $a){$v})",
    "inputJson": null
}
