Column formataing 'additionalRowClass' does not work

Question

I want to have the entire line in different color if the date field is earlier than now. I have found some JSON scripts, however the ones I found makes my column information disappear. The info is still there on edit but it is not visible and the colors does not change as well.

I have used the following code:

{
 "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
   "additionalRowClass": "=if([[$Traukinio_x0020_data] <= @now, 'sp-field-severity--severeWarning', '')"
}

also tried this:

{
"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
"additionalRowClass": "=if([[$Traukinio_x0020_data] <= @now, 'sp-field-severity--severeWarning', '')",
"elmType": "div",
"txtContent": "@currentField"
}

Can you please help me modify this?
