Linter fails on arg trailing comma

[Scony]

static func _is_agent_placement_position_valid(position, radius, existing_units, navigation_map_rid,):pass

Just had this happen to me. The following code works but it causes an error in gdlint.

func set_turn_order(
	next_turn_order: Array[Enums.MonsterPosition],
	next_move_order: Array[Move],
):
	current_turn_order = next_turn_order
	current_move_order = next_move_order

Traceback (most recent call last):

Gdlint works again after removing the trailing comma.

func set_turn_order(
	next_turn_order: Array[Enums.MonsterPosition], next_move_order: Array[Move]
):
	current_turn_order = next_turn_order
	current_move_order = next_move_order

Success: no problems found
