Pentaho Data Integration: ‘Execute SQL statement’ to create trigger

I'm trying to create a mysql trigger via an Execute SQL Statement step in my transformation. Below are the commands I'm attempting to run.

DROP TRIGGER IF EXISTS standing_actions_swap_before_insert_row_tr;
DELIMITER $$
CREATE DEFINER=`user`@`%` TRIGGER standing_actions_swap_before_insert_row_tr BEFORE INSERT ON `standing_actions_swap`
FOR EACH ROW 
BEGIN 
    SET NEW.id = CONCAT(NEW.acad_career, NEW.status, NEW.action); 
END
$$
DELIMITER ;

Unfortunately, for whatever reason, while the following works in various other db software suites (e.g. Sequel Pro, Aqua Data Studio), I always get an error in Pentaho Data Integration. I've tried omitting delimiters and checking and unchecking the Execute as a Single Statement box – unfortunately, it still no worky.

Any help is appreciated. Thanks!

Edit:

Here's is the stack trace:
