How to specify dynamic date field?

[darkbasic]

raw(`date_part('hour', "match"."start_date") >= date_part('hour', TIMESTAMP '$1')`,
  [new Date()])

"date/time field value out of range: \"$14\""

I specify that even manually formatting the date with format(minHour, 'yyyy-MM-dd HH:mm:ss X') leads to the same error, while avoiding parameters binding alltogether works perfectly (but it's not safe).
