Document Generation: Dynamic columns discard-if + context $ Title: discard-if: multiple conditions + , $ root context not working

I am using the Document Generation API with a Word template (dynamic table with table markers) and want to conditionally discard a column based on values coming from different levels of the input JSON.

I want to remove a column when either of the following conditions is true:

1. The current row’s product name equals a specific value (row-level context), OR
2. A root-level boolean flag show_pricing is false

{
  "data": {
    "approved_quote": true,
    "bypass_approval": false,
    "group_family": {
      "products": [
        {
          "name": "Product A",
          "items": [
            {
              "end_date": "31 Dec 2025",
              "prices": [{ "net_price": "$100" }]
            }
          ]
        },
        {
          "name": "Some Other Product",
          "items": [
            {
              "end_date": "15 Jan 2026",
              "prices": [{ "net_price": "$200" }]
            }
          ]
        }
      ]
    }
  },
  "show_pricing": false
}

 Template fragments I tried:

1. {{items.end_date:discard-if(expr(name = "Product A" or $.show_pricing = false))}}

2. {{items.end_date:discard-if(expr(show_pricing = false), $)}}

Tried 2nd one to test context tag is really working but, It didn’t work in my case
