    parameterizedBy: currentTimestamp # this contains a single row containing a "date" column
    properties:
      jsonObject: | # You can use Jinja functions and expressions in connector properties 
         [{ "dateJinja": "{{ func:date_format(func:current_datetime(), 'd-MMMM-y') }}",
           "dateSpark": "{{var.date}}" } ]
